Genes affected

NSG1 (HGNC:18790): (neuronal vesicle trafficking associated 1) Predicted to enable clathrin light chain binding activity. Involved in apoptotic process. Located in endoplasmic reticulum. [provided by Alliance of Genome Resources, Apr 2022]

NSG1 links:

STX18 (HGNC:15942): (syntaxin 18) This gene encodes a member of the syntaxin family of soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs) which is part of a membrane tethering complex that includes other SNAREs and several peripheral membrane proteins, and is involved in vesicular transport between the endoplasmic reticulum (ER) and the Golgi complex. The encoded protein is important for the organization of the smooth, rough, and exit site ER subdomains. A pseudogene of this gene has been identified. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2016]

Ambry Genetics

Oct 19, 2021

The c.539C>T (p.A180V) alteration is located in exon 5 (coding exon 4) of the D4S234E gene. This alteration results from a C to T substitution at nucleotide position 539, causing the alanine (A) at amino acid position 180 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
