Genes affected

TMEM134 (HGNC:26142): (transmembrane protein 134) Located in cytosol and perinuclear region of cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

TMEM134 links:

AIP (HGNC:358): (aryl hydrocarbon receptor interacting protein) The protein encoded by this gene is a receptor for aryl hydrocarbons and a ligand-activated transcription factor. The encoded protein is found in the cytoplasm as part of a multiprotein complex, but upon binding of ligand is transported to the nucleus. This protein can regulate the expression of many xenobiotic metabolizing enzymes. Also, the encoded protein can bind specifically to and inhibit the activity of hepatitis B virus. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2014]

Collection Method: clinical testing

The c.23T>A (p.F8Y) alteration is located in exon 1 (coding exon 1) of the TMEM134 gene. This alteration results from a T to A substitution at nucleotide position 23, causing the phenylalanine (F) at amino acid position 8 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
