A New Case of Rare Microdeletion 10q22.3q23 along with Mosaic Klinefelter Syndrome Associated with Facial Dysmorphic Finding, Atrial Ventricular Septal Defect, and Motor Retardation.

ABSTRACT: The chromosome 10q22.3q23.2 deletion syndrome is characterized by craniofacial dysmorphic features, developmental delay, congenital heart defect, and hand/foot abnormalities. In this study, we report a patient carrying a microdeletion of 7.5 Mb at 10q22.3q23.2 and in addition a mosaicism mos 47,XXY[47]/46,XY[23]. This male patient was 3 years and 3 months years old at the time of genetic evaluation. Atrial ventricular septal defect (AVSD), mild hypotonia, torticollis, and left-sided club foot were noticed after birth. The boy had surgical correction of the AVSD and the club foot. His dysmorphic features were frontal bossing, overfolded ear helix, hypertelorism, epicanthal folds, broad base of nose, flat nasal bridge, full cheeks, thick lips, micrognathia, and joint hyperextensibility.
