The molecular lesion is a C to A transversion at base pair 61,303,722 (v38) on chromosome 10, or base pair 6,045 in the GenBank genomic region NC_000076. This corresponds to nucleotide 1,513 in the mRNA sequence NM_011073, within exon 3 of 3 total exons. The mutation results in substitution of a premature stop codon for a tyrosine at residue 486 (Y486Ter). (J:216044)
