The c.854T>C (p.V285A) alteration is located in exon 9 (coding exon 9) of the LRRC1 gene. This alteration results from a T to C substitution at nucleotide position 854, causing the valine (V) at amino acid position 285 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
