The c.1067C>T (p.T356M) alteration is located in exon 3 (coding exon 2) of the KDF1 gene. This alteration results from a C to T substitution at nucleotide position 1067, causing the threonine (T) at amino acid position 356 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
