The c.5521T>A (p.Y1841N) alteration is located in exon 14 (coding exon 13) of the ZNFX1 gene. This alteration results from a T to A substitution at nucleotide position 5521, causing the tyrosine (Y) at amino acid position 1841 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
