SNaPshot Assay in Quantitative Detection of Allelic Nondisjunction in Down Syndrome.

Abstract excerpt

AIM: We wished to identify markers associated with allelic nondisjunction in nuclear families with Down syndrome (DS) offspring. Since the GRIK1 and GARS-AIRS-GART genes, mapping to chromosome 21q22.1, may be informative in this regard, we genotyped four single-nucleotide polymorphisms [30952599(A/G) rs363484; 30924733(A/G) rs363506; 34901423(A/G) rs2834235; 34877070(A/G) rs7283354] present in these genes using...
