The c.3809G>A (p.R1270Q) alteration is located in exon 3 (coding exon 2) of the KIAA1462 gene. This alteration results from a G to A substitution at nucleotide position 3809, causing the arginine (R) at amino acid position 1270 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
