Genes affected

ARV1 (HGNC:29561): (ARV1 homolog, fatty acid homeostasis modulator) this gene encodes a transmembrane protein that contains a conserved zinc ribbon motif at the N- terminus. A similar protein in mouse is thought to function in fatty acid homeostasis. Mutations in this gene are associated with early infantile epileptic encephalopathy 38. [provided by RefSeq, Nov 2016]

The c.118G>A (p.E40K) alteration is located in exon 1 (coding exon 1) of the ARV1 gene. This alteration results from a G to A substitution at nucleotide position 118, causing the glutamic acid (E) at amino acid position 40 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
