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]

The c.677A>G (p.D226G) alteration is located in exon 2 (coding exon 1) of the KLHL14 gene. This alteration results from a A to G substitution at nucleotide position 677, causing the aspartic acid (D) at amino acid position 226 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
