The c.469C>T (p.L157F) alteration is located in exon 3 (coding exon 1) of the KCTD16 gene. This alteration results from a C to T substitution at nucleotide position 469, causing the leucine (L) at amino acid position 157 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
