Collection Method:clinical testing

The c.980T>C (p.M327T) alteration is located in exon 5 (coding exon 4) of the SLC16A9 gene. This alteration results from a T to C substitution at nucleotide position 980, causing the methionine (M) at amino acid position 327 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
