|
Gene |
SGSH |
Chromosomal Location |
17q25.3 |
Allelic Variant 1 |
605270.0003; SANFILIPPO SYNDROME A |
Identified Mutation |
SER66TRP; A C-to-G transition results in the non-conservative amino acid exchange of ser66-to-trp (S66W). |
Remarks |
Deficient heparan sulfate sulfatase; normal alpha-D-glucosaminidase activity; donor subject is a compound heterozygote: one allele has a missense mutation (C>G) at nucleotide 209 (209C>G) of the SGSH gene [Ser66Trp(S66W)]; no changes detected in other allele |
