| Identified Mutation |
LEU32ARG; In a French patient with CDG Ia (212065), Vuillaumier-Barrot et al. (J Med Genet 37:579-580, 2000) identified a TA-to-GC substitution at nucleotide 95 in exon 2 of the PMM2 gene, resulting in a leu32-to-arg mutation.

F157S; CONGENITAL DISORDER OF GYLCOSYLATION, TYPE Ia |
| Identified Mutation |
PHE157SER |
| Remarks |
Clinically affected; abnormal isoelectric focusing pattern of serum transferrin; mild phenotype; donor subject is a compound heterozygote: one allele has two nucleotides mutated in exon 2 of the PMM2 gene [95TA>GC] resulting in a substitution of arginine for leucine at codon 32 [Leu32Arg (L32R)] and a second allele has a T>C transition at nucleotide 470 in exon 6 of the PMM2 gene [470T>C] resulting in a substitution of serine for phenylalanine at codon 157 [Phe157Ser (F157S)].
