Collection Method:clinical testing

The c.1094T>A (p.I365K) alteration is located in exon 6 (coding exon 1) of the ZNF83 gene. This alteration results from a T to A substitution at nucleotide position 1094, causing the isoleucine (I) at amino acid position 365 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
