Genes affected
KLHL14 (HGNC:29266): (kelch like family member 14) The protein encoded by this gene is a member of the Kelch-like gene family, whose members contain a BTB/POZ domain, a BACK domain, and several Kelch domains. The encoded protein possesses six Kelch domains and localizes to the endoplasmic reticulum, where it interacts with torsin-1A. [provided by RefSeq, Sep 2015]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 04, 2024The c.1199G>A (p.R400Q) alteration is located in exon 5 (coding exon 4) of the KLHL14 gene. This alteration results from a G to A substitution at nucleotide position 1199, causing the arginine (R) at amino acid position 400 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
