The c.184C>G (p.R62G) alteration is located in exon 2 (coding exon 1) of the LCE3E gene. This alteration results from a C to G substitution at nucleotide position 184, causing the arginine (R) at amino acid position 62 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
