| Remarks |
Clinically affected; deficient alpha-mannosidase; Finnish; mild clinical phenotype; psychomotor retardation after age 1 year; recurring infections; hearing loss; impaired speech; coarse facial features; donor subject is a compound heterozygote: one allele has a C>T transition in exon 15 of the MAN2B1 gene resulting in the substitution of a termination signal for glutamine at codon 639 [Gln639Ter (Q639X)]; the second allele has a C>T transition at nucleotide 2248 in exon 18 (2248C>T) resulting in the substitution of tryptophan for arginine at codon 750 [Arg750Trp (R750W)] |
