The c.1930C>T (p.P644S) alteration is located in exon 15 (coding exon 15) of the STRN3 gene. This alteration results from a C to T substitution at nucleotide position 1930, causing the proline (P) at amino acid position 644 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
