The c.1601C>G (p.A534G) alteration is located in exon 5 (coding exon 4) of the KANK3 gene. This alteration results from a C to G substitution at nucleotide position 1601, causing the alanine (A) at amino acid position 534 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
