The c.107A>G (p.K36R) alteration is located in exon 2 (coding exon 1) of the LCE1C gene. This alteration results from a A to G substitution at nucleotide position 107, causing the lysine (K) at amino acid position 36 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
