The c.809A>G (p.Y270C) alteration is located in exon 9 (coding exon 9) of the LRRC72 gene. This alteration results from a A to G substitution at nucleotide position 809, causing the tyrosine (Y) at amino acid position 270 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
