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 03, 2022The c.323A>G (p.Y108C) alteration is located in exon 4 (coding exon 4) of the KLHDC1 gene. This alteration results from a A to G substitution at nucleotide position 323, causing the tyrosine (Y) at amino acid position 108 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
