Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2 PP3_Moderate

The NM_018467.4(USE1):​c.752T>C​(p.Phe251Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000657 in 152,246 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. F251C) has been classified as Uncertain significance.

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.
