Holoprosencephaly, ectrodactyly, and bilateral cleft of lip and palate: exclusion of SHH, TGIF, SIX3, GLI2, TP73L, and DHCR7 as candidate genes.
We describe a Brazilian boy with semilobar holoprosencephaly, ectrodactyly, bilateral cleft of lip and palate, and severe mental retardation. The karyotype was normal and the screening for mutations in the genes SHH, TGIF, SIX3, GLI2, TP73L, and DHCR7 did not show any change. This rare condition was described previously in seven male patients. Clinical and genetic aspects are discussed.
