The c.514C>G (p.L172V) alteration is located in exon 1 (coding exon 1) of the LRRC18 gene. This alteration results from a C to G substitution at nucleotide position 514, causing the leucine (L) at amino acid position 172 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
