The c.302C>T (p.P101L) alteration is located in exon 2 (coding exon 1) of the CCSAP gene. This alteration results from a C to T substitution at nucleotide position 302, causing the proline (P) at amino acid position 101 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
