The c.238G>A (p.G80R) alteration is located in exon 2 (coding exon 1) of the LCE3D gene. This alteration results from a G to A substitution at nucleotide position 238, causing the glycine (G) at amino acid position 80 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
