Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2 BP4

The ENST00000233025.11(SPCS1):​c.47C>G​(p.Ser16Cys) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S16Y) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 33)
• Consequence: SPCS1 ENST00000233025.11 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 3.78

Genes affected

SPCS1 (HGNC:23401): (signal peptidase complex subunit 1) Predicted to enable peptidase activity and ribosome binding activity. Involved in viral protein processing and virion assembly. Is integral component of endoplasmic reticulum membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.3077342).
