Abstract excerpt
We report a Mexican girl showing the full blown clinical picture of mucopolysaccharidosis type II (MPSII). Iduronate-2-sulfatase (IDS) activity was low and she carried a heterozygous de novo c.1327C>T transition in exon 9, that changes codon 443 for a premature stop (TGA; p.Arg443(*)). Analysis of X-chromosome inactivation in androgen receptor (AR) locus showed a highly skewed ratio of 92:8 suggesting a...
