Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.197T>A (p.M66K) alteration is located in exon 3 (coding exon 2) of the SLC16A4 gene. This alteration results from a T to A substitution at nucleotide position 197, causing the methionine (M) at amino acid position 66 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
