| MUTATION VERIFICATION |
Myerowitz (Proc Natl Acad Sci USA 85:3955 1988) observed 1 normal alpha chain allele and 1 alpha chain allele with a splice junction mutation consisting of a cytidine residue substituting for a guanosine as the first nucleotide at the 5 prime boundary of intron 12. Arpaia et al (NATURE 333:85-86 1988) also observed that this Tay-Sachs disease heterozygote had the same splice junction mutation a DdeI restriction site as his affected daughter (GM02968). Myerowitz and Costigan (J Biol Chem 263:18587-18589 1988) reported that this patient lacked the 4 base pair insertion in exon 11 of the alpha chain gene which was found in his spouse and affected daughter. |

| Remarks |
Ashkenazi; clinically unaffected; 1 alpha chain allele has a splice junction mutation; neither alpha chain allele has a 4 bp insertion in exon 11; father of GM02968A |
