The c.874C>T (p.P292S) alteration is located in exon 6 (coding exon 6) of the CCDC136 gene. This alteration results from a C to T substitution at nucleotide position 874, causing the proline (P) at amino acid position 292 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
