Genes affected

TMED1 (HGNC:17291): (transmembrane p24 trafficking protein 1) This gene belongs to the TMED (transmembrane emp24 domain-containing) protein family, which is involved in the vesicular trafficking of proteins. The protein encoded by this gene was identified by its interaction with interleukin 1 receptor-like 1 (IL1RL1) and may play a role in innate immunity. This protein lacks any similarity to other interleukin 1 ligands. Alternative splicing results in multiple transcript variants of this gene. [provided by RefSeq, Jul 2013]

The c.460A>G (p.I154V) alteration is located in exon 3 (coding exon 3) of the TMED1 gene. This alteration results from a A to G substitution at nucleotide position 460, causing the isoleucine (I) at amino acid position 154 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
