The c.4214C>T (p.T1405I) alteration is located in exon 35 (coding exon 35) of the KCP gene. This alteration results from a C to T substitution at nucleotide position 4214, causing the threonine (T) at amino acid position 1405 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
