The c.1456G>A (p.V486I) alteration is located in exon 7 (coding exon 6) of the LRRIQ3 gene. This alteration results from a G to A substitution at nucleotide position 1456, causing the valine (V) at amino acid position 486 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
