The c.2402A>T (p.K801I) alteration is located in exon 10 (coding exon 10) of the ZC3H3 gene. This alteration results from a A to T substitution at nucleotide position 2402, causing the lysine (K) at amino acid position 801 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
