Submissions by phenotype
not specified Uncertain:1
The c.512G>A (p.R171H) alteration is located in exon 2 (coding exon 1) of the KCTD4 gene. This alteration results from a G to A substitution at nucleotide position 512, causing the arginine (R) at amino acid position 171 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
