The c.966A>C (p.E322D) alteration is located in exon 8 (coding exon 7) of the STK17B gene. This alteration results from a A to C substitution at nucleotide position 966, causing the glutamic acid (E) at amino acid position 322 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
