The c.845C>T (p.T282I) alteration is located in exon 5 (coding exon 4) of the ZNF614 gene. This alteration results from a C to T substitution at nucleotide position 845, causing the threonine (T) at amino acid position 282 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
