The c.3149A>G (p.D1050G) alteration is located in exon 19 (coding exon 18) of the RC3H2 gene. This alteration results from a A to G substitution at nucleotide position 3149, causing the aspartic acid (D) at amino acid position 1050 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
