The c.641G>T (p.W214L) alteration is located in exon 2 (coding exon 2) of the LRRC3C gene. This alteration results from a G to T substitution at nucleotide position 641, causing the tryptophan (W) at amino acid position 214 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
