The c.944C>T (p.P315L) alteration is located in exon 8 (coding exon 8) of the SNAPC1 gene. This alteration results from a C to T substitution at nucleotide position 944, causing the proline (P) at amino acid position 315 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
