The c.287A>G (p.Q96R) alteration is located in exon 2 (coding exon 1) of the FAM198B gene. This alteration results from a A to G substitution at nucleotide position 287, causing the glutamine (Q) at amino acid position 96 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
