| Remarks |
Clinically affected; decreased alpha dystroglycan; diagnosed by muscle biopsy and muscle imaging (MRI); type II lissencephaly (predominant pachygyria-frontal>occipital); possible polymicrogyria; inferior vermis hypoplasia; small pons; inferior vermis hypoplasia; patchy white matter abnormalities in higher parietal white matter; small tectum; mental retardation; turned in bed without assistance at age 3 months; sat without assistance at age 6 months; walked indoors without assistance at age 2 years; ejection fraction > 60%; donor subject is a compound heterozygote: the paternal allele has a 74 kb deletion {chromosome 22q12.3: [32330175 (SNP rs2239746)]- [32403758 (SNP rs2267255)]} of the LARGE gene including coding exons; the maternal allele has a G>A transition at nucleotide 1525 in exon 13 (1525G>A) resulting in the substitution of lysine for glutamic acid at codon 509 [Glu509Lys (E509K)]. |
