The c.1090A>G (p.I364V) alteration is located in exon 6 (coding exon 6) of the FCAMR gene. This alteration results from a A to G substitution at nucleotide position 1090, causing the isoleucine (I) at amino acid position 364 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
