The c.5042T>A (p.I1681N) alteration is located in exon 26 (coding exon 26) of the ZFC3H1 gene. This alteration results from a T to A substitution at nucleotide position 5042, causing the isoleucine (I) at amino acid position 1681 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
