| Remarks |
Clinically affected; delivered via C-section at 35 weeks gestation; hospitalized 10 days for feeding issues; splenomegaly first noted at 2 years of age; global developmental delay more pronounced in fine and gross motor skills with early signs of ataxia; hepatomegaly noted at age 3 years and 9 months; persistent mild elevated AST and LDH; elevated DHEA; mild leukopenia; regression of speech; see GM22871 Fibroblast; affected monozygotic twin sister (GM22227); donor subject has a 1 bp deletion in exon 12 of the NPC1 gene (1920delG) inherited from her mother; her paternal mutation is a missense mutation (IVS9-1009G>A) |
