Oct 01, 2024

The c.10C>T (p.P4S) alteration is located in exon 1 (coding exon 1) of the SNAPC1 gene. This alteration results from a C to T substitution at nucleotide position 10, causing the proline (P) at amino acid position 4 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
