Collection Method:clinical testing

The c.1028T>A (p.I343N) alteration is located in exon 8 (coding exon 7) of the STK17B gene. This alteration results from a T to A substitution at nucleotide position 1028, causing the isoleucine (I) at amino acid position 343 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
