Genes affected
KLHL42 (HGNC:29252): (kelch like family member 42) Contributes to ubiquitin-protein transferase activity. Involved in proteasome-mediated ubiquitin-dependent protein catabolic process; protein polyubiquitination; and regulation of microtubule-based process. Part of Cul3-RING ubiquitin ligase complex.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2023The c.40C>G (p.R14G) alteration is located in exon 1 (coding exon 1) of the KLHL42 gene. This alteration results from a C to G substitution at nucleotide position 40, causing the arginine (R) at amino acid position 14 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
