The mutation is a T to C transition at base pair 165,062,301 (v38) on chromosome 2, or base pair 6,698 in the GenBank genomic region NC_000068. The mutation corresponds to residue 139 in the mRNA sequences NM_011611 (variant 1; within exon 2 of 9 total exons), NM_170703 (variant 2; within exon 2 of 8 total exons), NM_170704 (variant 4; within exon 2 of 9 total exons), and NM_170702 (variant 5; within exon 2 of 8 total exons). The mutation results in an cysteine (C) to arginine (R) substitution at position 23 (C23R). (J:221482)
