The c.1346A>G (p.D449G) alteration is located in exon 13 (coding exon 12) of the FAM114A2 gene. This alteration results from a A to G substitution at nucleotide position 1346, causing the aspartic acid (D) at amino acid position 449 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
