Neurological features of 14q24-q32 interstitial deletion: report of a new case.

ABSTRACT: BACKGROUND:Interstitial deletions of the long arm of chromosome 14 involving the 14q24-q32 region have been reported in less than 20 patients. Previous studies mainly attempted to delineate recognizable facial dysmorphisms; conversely, descriptions on neurological features are limited to the presence of cognitive and motor delay, but no better characterization exists. CASE PRESENTATION:In this paper we report on a patient with a de novo interstitial deletion of 5.5 Mb at 14q24.3-q31.1. The deletion encompasses 84 genes, including fourteen Mendelian genes. He presented with dysmorphic face, developmental delay, paroxysmal non-epileptic events and, subsequently, epilepsy. CONCLUSIONS:The clinical and molecular evaluation of this patient and the review of the literature expand the phenotype of 14q23-q32 deletion syndrome to include paroxysmal non-epileptic events and infantile-onset focal seizures.

A New Case of an Extremely Rare 3p21.31 Interstitial Deletion.

Project description:Interstitial 3p21.31 deletions have been very rarely reported. We describe a 7-year-old boy with global developmental delay, specific facial characteristics, hydronephrosis, and hypothyreosis with a de novo deletion of 3p21.31, encompassing 29 OMIM genes. Despite the wide use of microarrays, no similar case has been reported in the literature so far. Five overlapping cases are deposited in the DECIPHER database, 2 of which have significant overlapping chromosomal aberrations. They both share some phenotypic characteristics with our case, e.g. developmental delay, intellectual disability and facial dysmorphism (arched eyebrows, hypertelorism, low-set ears, and a large nose tip). In addition, loss-of-function mutations in the SETD2 gene (OMIM 612778) of the deleted region have been described in 3 patients, presenting with some similar clinical features, namely overgrowth, intellectual disability, speech delay, hypotonia, autism, and epilepsy. Therefore, SETD2 may explain part of the phenotype in our case. We focused on 3 other genes in the deleted region, based on their known functions, namely CSPG5 (OMIM 606775), PTH1R (OMIM 168468) and SMARCC1 (OMIM 601732), and assessed their potentially important role in describing the patient's phenotype. Additional cases with haploinsufficiency of this region are needed to elucidate further genotype-phenotype correlations.

A boy with 13.34-Mb interstitial deletion of chromosome 4p15: A new case report and review of the literature.

Project description:To date, >40 cases have been described with interstitial deletions involving the 4p15 region.We report a case of a 3-year-old boy with an interstitial de novo deletion of approximately 13.34 Mb in 4p15.1-15.31 having mild developmental delay and multiple minor congenital abnormalities.This case presents a clinical manifestation that is similar but not identical to other reported cases. In this report, we have provided a detailed description of a 3-year-old patient with an interstitial 4p deletion and mildly affected phenotype. We discuss the possible involvement of SLIT2, KCNIP4, and LGI2 in cortical development and RBPJ in skeletal abnormalities.

A novel interstitial deletion of chromosome 2q21.1-q23.3: Case report and literature review.

Project description:BACKGROUND:Interstitial deletions of 2q are rare. Those that have been reported show varying clinical manifestations according to the size of the deletion and the genomic region involved. METHOD AND RESULTS:We describe a preterm male harboring a novel interstitial deletion encompassing the 2q21.2-q23.3 region of 2q, a deletion that has not been described previously. The patient had multiple congenital anomalies including agenesis of the corpus callosum, congenital cardiac defects, bilateral hydronephrosis, spontaneous intestinal perforation, hypospadias and cryptorchidism, sacral dimple and rocker-bottom feet. Array comparative genomic hybridization (aCGH) analysis revealed a de novo >18 Mb deletion at 2q21.1-q23.3, a region that included (605802, 611472 and 604593) OMIM genes. CONCLUSION:To the best of our knowledge this is the first report of a de novo interstitial deletion at 2q21.1-q23.3 in which haploinsufficiency of dose-sensitive genes is shown to contribute to the patient's phenotype.

Cervical Spine Malformations Associated With a 5q34-5q35.2 Micro-interstitial Deletion: A Case Report.

Project description:We report a female proband carrying a de novo 5q34-q35.2 deletion breakpoint, and review the unique skeletal phenotype and possible genotype related to this mutation. The patient presented with a persistent head tilt and limited head rotation. Non-contrast-enhanced three-dimensional computed tomography of the cervical spine revealed several malformations including a bone cleft in the right pars interarticularis, a bone defect in both C5 lamina and the transverse foramen at C2-C3, agenesis of the right articular process of C5, bony fusion of C4-C5, and subluxation of the craniocervical joints. Several deformities of the cervical spine seen in this patient have not been associated with the 5q deletion. A review of 5q-related mutations suggests that abnormalities associated with MSX2 gene might cause cervical spine abnormalities.

Case report: A new <i>de novo</i> 6q21q22.1 interstitial deletion case in a girl with cerebellar vermis hypoplasia and developmental delay and literature review.

Project description:Interstitial deletions involving 6q chromosomal region are rare. Less than 30 patients have been described to date, and fewer have been characterized by high-resolution techniques, such as chromosomal microarray. Deletions involving 6q21q22.1 region are associated with an extremely wide and heterogeneous clinical spectrum, thus genotype-phenotype correlation based on the size of the rearranged region and on the involved genes is complex, even among individuals with overlapping deletions. Here we describe the phenotypic and molecular characterization of a new 6q interstitial deletion in a girl with developmental delay, intellectual disability, cerebellar vermis hypoplasia, facial peculiar characteristics, ataxia and ocular abnormalities. Microarray analysis of the proposita revealed a 7.9 Mb interstitial de novo deletion at 6q21q22.1 chromosomal region, which spanned from nucleotides 108,337,770 to 116,279,453 (GRCh38/hg38). The present case, alongside with a systematic review of the literature, provides further evidence that could aid to the definition of the Smallest Region of Overlap and of the genomic traits that are associated with particular phenotypes, focusing on neurological findings and especially on cerebellar anomalies.

Case Report: Molecular Profiling Facilitates the Diagnosis of a Challenging Case of Lung Cancer with Choriocarcinoma Features

Project description:Accurate diagnoses are crucial in determining the most effective treatment across different cancers. In challenging cases, morphology-based traditional pathology methods have important limitations, while molecular profiling can provide valuable information to guide clinical decisions. We present a 35-year female with lung cancer with choriocarcinoma features. Her disease involved the right lower lung, brain, and thoracic lymph nodes. The pathology from brain metastasis was reported as “metastatic choriocarcinoma” (a germ cell tumor) by local pathologists. She initiated carboplatin and etoposide, a regimen for choriocarcinoma. Subsequently, her case was assessed by pathologists from an academic cancer center, who gave the diagnosis of “adenocarcinoma with aberrant expression of β-hCG” and finally pathologists at our hospital, who gave the diagnosis of “poorly differentiated carcinoma with choriocarcinoma features”. Genomic profiling detected a KRAS G13R mutation and transcriptomics profiling was suggestive of lung origin. The patient was treated with carboplatin/paclitaxel/ipilimumab/nivolumab followed by consolidation radiation therapy. She had no evidence of progression to date, 13 months after the initial presentation. The molecular profiling could facilitate diagnosing of challenging cancer cases. In addition, chemoimmunotherapy and local consolidation radiation therapy may provide promising therapeutic options for patients with lung cancer exhibiting choriocarcinoma features.

13q interstitial deletion in a moroccan child with hereditary retinoblastoma and intellectual disability: A case report.

Project description:Retinoblastoma is the most common malignant tumor of the eye in children (incidence:1/15,000 to 1/20,000 births), with a sex ratio of 1,5/1. Retinoblastoma, in its inherited form, is a disease caused by a syndrome of genetic predisposition to cancer. The RB1 gene, a tumor suppressor gene, is localized at 13q14. This case report shows the indication of the cytogenetic analysis in the management of patients with retinoblastoma, and the interest of a genetic counseling. We report the medical observation of a five and a half years old patient who was followed in the medical genetic's department for intellectual disability: associated with facial dysmorphia. The cytogenetic study objectified the presence of an interstitial deletion of the long arm of chromosome 13: 46, XX, del (13) (q14q22). A genetic counseling, with study of the karyotype of the parents is planned, specially to search for a balanced insertion: 13q14 insertion and deletion. In addition, the patient has been followed since the age of 9 months at the pediatric ophthalmology department for a bilateral retinoblastoma, in remission. A subject carry in constitutional mutation of the RB1 gene has a greater than 90% risk of developing retinoblastoma, and moreover has a genetic predisposition to secondary tumors. This medical observation shows the benefit of the constitutional cytogenetic study for patients with retinoblastoma, in particular in the event of bilateral retinoblastoma. The monitoring of psychomotor development must supplement the ophthalmological monitoring of these patients, with a systematic genetic counseling.

Interstitial 11q deletion in a patient with Sprengel's deformity: a case report and review of the literature.

Project description:BackgroundInterstitial chromosome 11 long arm deletions (11q13-q23) represent a rare cytogenetic abnormality characterized by non-specific clinical features including intellectual disability and several malformations without a clear genotype-phenotype correlation. We describe the first case of interstitial 11q deletion identified in a boy with Sprengel's deformity and provide a review of the literature.Case presentationWe report a 9-year-old boy with congenital scapular deformity, iris and chorioretinal coloboma, normal intelligence, and a history of mild motor development delay. The karyotype showed a de novo large 11q deletion. Fluorescence in situ hybridization (FISH) confirmed that the deletion is interstitial, and array comparative genomic hybridization (aCGH) revealed a loss of 25.8 Mb encompassing the 11q14.1-q22.3 region.ConclusionsThe present case and the literature review of 61 previously published cases highlight the clinical heterogeneity and the lack of genotype-phenotype correlation in interstitial 11q deletions. Sprengel's deformity found in our patient might be a new finding in 11q deletions or, more probably, a fortuitous association.

Chromosome 3p Inverted Duplication with Terminal Deletion: Second Postnatal Case Report with Additional Clinical Features.

Project description:Distal deletions and duplications of 3p are individually well-characterized chromosome abnormalities. Here, we report an inverted duplication of 3p with an adjacent terminal 3p deletion in a 17-month-old girl who had prenatal intrauterine growth restriction and cardiac defects. Other findings included hemangiomas, neutropenia, umbilical hernia, hypotonia, gross motor delay, microcephaly, and ptosis. Family history was noncontributory. Microarray analysis revealed a 5.37 Mb deletion of chromosome bands 3p26.1 to 3p26.3 and a 13.68 Mb duplication of 3p24.3 to 3p26.1. FISH analysis confirmed that the duplication was inverted. Upon literature review, only one postnatal patient and one second trimester pregnancy have been reported with this finding. Many of our patient's features are present in both 3p deletion and 3p duplication syndromes, including congenital heart disease, growth restriction, microcephaly, hypotonia, and developmental delay. Our patient has additional features not commonly reported in 3p deletion or duplication patients, such as aortic dilation, hemangiomas, and neutropenia. The identification of this patient contributes to additional understanding of features associated with concurrent deletion and inverted duplication in the distal 3p chromosome. This report may assist clinicians working with patients who have constellations of similar features or similar cytogenomic abnormalities.
