The c.800T>C (p.M267T) alteration is located in exon 4 (coding exon 3) of the KLHL8 gene. This alteration results from a T to C substitution at nucleotide position 800, causing the methionine (M) at amino acid position 267 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
