The c.440G>A (p.G147D) alteration is located in exon 4 (coding exon 4) of the FAM213B gene. This alteration results from a G to A substitution at nucleotide position 440, causing the glycine (G) at amino acid position 147 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
