The c.781A>T (p.S261C) alteration is located in exon 2 (coding exon 1) of the KIAA1958 gene. This alteration results from a A to T substitution at nucleotide position 781, causing the serine (S) at amino acid position 261 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
