The c.1363T>C (p.S455P) alteration is located in exon 7 (coding exon 6) of the KLHL8 gene. This alteration results from a T to C substitution at nucleotide position 1363, causing the serine (S) at amino acid position 455 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
