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.1448A>C (p.E483A) alteration is located in exon 7 (coding exon 6) of the KLHL14 gene. This alteration results from a A to C substitution at nucleotide position 1448, causing the glutamic acid (E) at amino acid position 483 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
