ATR-16 syndrome is due to alterations on chromosome 16p13.3, and is usually accompanied by alpha-thalassemia, mild-moderate mental retardation, dysmorphic facial features, skeletal and genitourinary malformations. There are no references of the combination of ATR-16 syndrome and osteosarcoma in the literature. Osteosarcoma usually has a complex karyotype, characterized by a high degree of heterogeneity of chromosomal aberrations, among which is the involvement of chromosome 16. We report a case of a patient with ATR-16 syndrome diagnosed with femoral osteosarcoma.

Osteosarcoma is the most common malignant bone tumor in adolescents and young adults. Most osteosarcomas are sporadic but the risk of osteosarcoma is also increased by germline variants in TP53, RB1 and RECQL4 genes. ATRX germline variations are responsible for the rare genetic disorder X-linked alpha-thalassemia mental retardation (ATR-X) syndrome characterized by severe developmental delay and alpha-thalassemia but no obvious increased risk of cancer. Here we report two children with ATR-X syndrome who developed osteosarcoma. Notably, one of the children developed two osteosarcomas separated by 10 years. Those two cases raise the possibility that ATRX germline variant could be associated with an increased risk of osteosarcoma.
