Trisomy 13

Patau syndrome

Trisomy 13 (also called Patau syndrome) is a genetic disorder in which a person has 3 copies of genetic material from chromosome 13, instead of the usual 2 copies. Rarely, the extra material may be attached to another chromosome (translocation).

Extra digits may be present as an isolated finding, or they may occur as part of a syndrome, in which case other abnormalities are usually present.

Syndactyly

Fingers or toes (digits) may be fused together (syndactyly) or the webbing between them (inter-digital webbing) may extend far up the digits. Syndactyly is seen commonly between the second and third toes, and may sometimes be associated with a syndrome.
