Collection Method: clinical testing

The c.337T>A (p.L113I) alteration is located in exon 4 (coding exon 4) of the ZNF90 gene. This alteration results from a T to A substitution at nucleotide position 337, causing the leucine (L) at amino acid position 113 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
