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 GeneticsJul 13, 2022The c.140G>A (p.G47D) alteration is located in exon 1 (coding exon 1) of the KLHL42 gene. This alteration results from a G to A substitution at nucleotide position 140, causing the glycine (G) at amino acid position 47 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
