[Osteosarcoma and ATR-16 syndrome: association or coincidence?]

Abstract

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.

Keywords: ATR-16 syndrome; Chromosome 16p; Cromosoma 16p; Osteosarcoma; Síndrome ATR-16.
