Genes affected

USE1 (HGNC:30882): (unconventional SNARE in the ER 1) Predicted to enable SNAP receptor activity. Predicted to be involved in several processes, including lysosomal transport; protein catabolic process; and retrograde vesicle-mediated transport, Golgi to endoplasmic reticulum. Predicted to act upstream of or within endoplasmic reticulum tubular network organization and regulation of ER to Golgi vesicle-mediated transport. Located in endoplasmic reticulum.

Collection Method: clinical testing

The c.467C>T (p.A156V) alteration is located in exon 7 (coding exon 7) of the USE1 gene. This alteration results from a C to T substitution at nucleotide position 467, causing the alanine (A) at amino acid position 156 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
