The c.451G>A (p.V151I) alteration is located in exon 2 (coding exon 1) of the FAM110A gene. This alteration results from a G to A substitution at nucleotide position 451, causing the valine (V) at amino acid position 151 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
