The c.196A>G (p.I66V) alteration is located in exon 3 (coding exon 1) of the FAM114A1 gene. This alteration results from a A to G substitution at nucleotide position 196, causing the isoleucine (I) at amino acid position 66 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
