The c.590C>G (p.S197W) alteration is located in exon 4 (coding exon 3) of the KIAA1644 gene. This alteration results from a C to G substitution at nucleotide position 590, causing the serine (S) at amino acid position 197 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
