The c.562A>G (p.I188V) alteration is located in exon 7 (coding exon 7) of the FAM92B gene. This alteration results from a A to G substitution at nucleotide position 562, causing the isoleucine (I) at amino acid position 188 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
