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]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 26, 2023The c.217C>T (p.P73S) alteration is located in exon 2 (coding exon 2) of the ARV1 gene. This alteration results from a C to T substitution at nucleotide position 217, causing the proline (P) at amino acid position 73 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
