Ring chromosome 13 is one of such disorders in which the genotype-phenotype correlation is stronger by virtue of the accumulating literature. It can be associated with multiple congenital abnormalities and severe mental retardation. We report a case with mosaic ring chromosome 13 whose prenatal ultrasound revealed bilateral ventriculomegaly. Anal atresia, unidentifiable external genitalia, and an absent thumb were observed in the postmortem examination.eninfo:eu-repo/semantics/closedAccessAbnormal genitaliaAbsent thumbAnal atresiaMosaicRing chromosome 13Anal atresia, abnormal genitalia, and absent thumb: Congenital malformations associated with mosaic ring chromosome 13Article242157160240322852-s2.0-84884321378N/A
