Chromosome 19q13.11 deletion syndrome, distal is a congenital condition resulting from a deletion in the distal region of the long arm of chromosome 19. It presents as a multi-system disorder with characteristic findings that affect the skin, growth, and neurodevelopment. Affected individuals typically exhibit features from birth such as growth delay, feeding difficulties, and distinctive facial and limb findings. The condition is considered sporadic and follows an autosomal dominant pattern, and while exact prevalence estimates are not specified, it is regarded as rare.

The clinical presentation of this condition is marked by several defining features. Nearly all affected individuals have aplasia cutis congenita of the scalp, feeding difficulties in infancy, intrauterine growth retardation, growth delay, sparse eyebrows and hair, clinodactyly of the 5th finger, microcephaly, intellectual disability, and global developmental delay, indicating significant cognitive and developmental involvement. Additional findings that occur in a subset of individuals include a single umbilical artery, solitary median maxillary central incisor, cutaneous finger syndactyly, bifid scrotum, nail dysplasia, overlapping toe, and febrile seizures. Not all individuals experience all of these features, and their severity can vary considerably.

The precise genetic basis of chromosome 19q13.11 deletion syndrome, distal is still under investigation. The condition is described as sporadic and follows an autosomal dominant pattern, meaning the genetic change typically occurs de novo without a prior family history. This pattern implies that the deletion is not usually inherited from a parent, and recurrence in siblings is unlikely. Families are encouraged to seek genetic counseling to better understand recurrence risks and potential implications for future family planning.
