The c.274C>T (p.P92S) alteration is located in exon 2 (coding exon 2) of the CDRT15L2 gene. This alteration results from a C to T substitution at nucleotide position 274, causing the proline (P) at amino acid position 92 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
