The c.65C>T (p.P22L) alteration is located in exon 2 (coding exon 1) of the CHMP7 gene. This alteration results from a C to T substitution at nucleotide position 65, causing the proline (P) at amino acid position 22 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
