De novo myelodysplastic syndrome in a Rothmund-Thomson Syndrome patient with novel pathogenic RECQL4 variants.

ABSTRACT: Rothmund-Thomson syndrome (RTS) is a rare autosomal-recessive disorder with clinical features consisting of rash, poikiloderma, sparse hair, short stature, juvenile cataracts, skeletal abnormalities, and cancer predisposition. Genetic studies involving detection of pathogenic RECQL4 variants provide the diagnostic certitude. Osteosarcoma was found in two-thirds RECQL4-mutated RTS patients, while hematological malignancies were rarely reported. The variant diversity of RECQL4 gene has not been fully identified and mutations associated with hematologic malignancies are not well described. In this study, we presented a pedigree of RTS from a Chinese family, among which the proband was diagnosed with de novo myelodysplastic syndrome (MDS). Comprehensive medical examination
