The c.499C>T (p.P167S) alteration is located in exon 6 (coding exon 6) of the TMEM134 gene. This alteration results from a C to T substitution at nucleotide position 499, causing the proline (P) at amino acid position 167 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
