The c.2770G>A (p.V924I) alteration is located in exon 20 (coding exon 20) of the KIAA1324L gene. This alteration results from a G to A substitution at nucleotide position 2770, causing the valine (V) at amino acid position 924 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
