The c.5479A>G (p.I1827V) alteration is located in exon 14 (coding exon 13) of the ZNFX1 gene. This alteration results from a A to G substitution at nucleotide position 5479, causing the isoleucine (I) at amino acid position 1827 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
