The c.493C>T (p.P165S) alteration is located in exon 1 (coding exon 1) of the KLHDC7A gene. This alteration results from a C to T substitution at nucleotide position 493, causing the proline (P) at amino acid position 165 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
