The c.905A>G (p.H302R) alteration is located in exon 9 (coding exon 9) of the FAM92B gene. This alteration results from a A to G substitution at nucleotide position 905, causing the histidine (H) at amino acid position 302 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
