The c.844C>T (p.P282S) alteration is located in exon 8 (coding exon 7) of the STK17B gene. This alteration results from a C to T substitution at nucleotide position 844, causing the proline (P) at amino acid position 282 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
