The c.894C>A (p.D298E) alteration is located in exon 4 (coding exon 2) of the KCTD16 gene. This alteration results from a C to A substitution at nucleotide position 894, causing the aspartic acid (D) at amino acid position 298 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
