not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 07, 2024The c.4353C>G (p.C1451W) alteration is located in exon 36 (coding exon 36) of the KCP gene. This alteration results from a C to G substitution at nucleotide position 4353, causing the cysteine (C) at amino acid position 1451 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
