The c.779G>A (p.R260Q) alteration is located in exon 2 (coding exon 1) of the LRRC4C gene. This alteration results from a G to A substitution at nucleotide position 779, causing the arginine (R) at amino acid position 260 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
