The c.548G>A (p.G183E) alteration is located in exon 3 (coding exon 3) of the FAM210B gene. This alteration results from a G to A substitution at nucleotide position 548, causing the glycine (G) at amino acid position 183 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
