H405Y; SMITH-LEMLI-OPITZ SYNDROME |
| Identified Mutation |
HIS405TYR |
| Remarks |
46,XX in leukocytes; failure to thrive, developmental delay, hypotonia, microcephaly, micrognathia, simian creases, and partial syndactyly; negative family history; see GM05789 Lymphoid; donor subject is a compound heterozygote: one allele has a G>T transversion at nucleotide 413 of the DHCR7 gene (c.413G>T) resulting in the substitution of valine for glycine at codon 138 [Gly138Val (G138V)] and the second allele has a C>T transition at nucleotide 1213 (c.1213C>T) resulting in the substitution of tyrosine for histidine at codon 405 [His405Tyr (H405Y)] |
