The c.779C>G (p.S260W) alteration is located in exon 8 (coding exon 8) of the TMEM161A gene. This alteration results from a C to G substitution at nucleotide position 779, causing the serine (S) at amino acid position 260 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
