| Chromosomal Location |
12q23.3 |
| Allelic Variant 1 |
Y1079fsX1081; MUCOLIPIDOSIS II |
| Identified Mutation |
4-BP DUP, 3395CTAC |
| Remarks |
Arab; clinically unaffected mother of GM02013D; GlcNAc-Phosphotransferase activity = 58% (measured as specific activity in cell lysate and reported as percentage of activity in normal fibroblasts); donor subject has one allele which has a duplication in exon 16 of the GNPTAB gene [3395_3398dupCTAC] resulting in a frameshift and truncation of the protein in the beta subunit [Y1079fsX1081]. |
