The c.155C>G (p.A52G) alteration is located in exon 1 (coding exon 1) of the LRCH3 gene. This alteration results from a C to G substitution at nucleotide position 155, causing the alanine (A) at amino acid position 52 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
