The c.1915C>T (p.R639W) alteration is located in exon 14 (coding exon 14) of the STRN4 gene. This alteration results from a C to T substitution at nucleotide position 1915, causing the arginine (R) at amino acid position 639 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
