Genes affected
KLHDC1 (HGNC:19836): (kelch domain containing 1) Enables ubiquitin ligase-substrate adaptor activity. Involved in ubiquitin-dependent protein catabolic process via the C-end degron rule pathway. Is active in Cul5-RING ubiquitin ligase complex and cytosol. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 07, 2023The c.227G>C (p.C76S) alteration is located in exon 3 (coding exon 3) of the KLHDC1 gene. This alteration results from a G to C substitution at nucleotide position 227, causing the cysteine (C) at amino acid position 76 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
