The c.1462C>T (p.P488S) alteration is located in exon 5 (coding exon 4) of the SLC16A8 gene. This alteration results from a C to T substitution at nucleotide position 1462, causing the proline (P) at amino acid position 488 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
