Genes affected

IFI35 (HGNC:5399): (interferon induced protein 35) Enables identical protein binding activity. Involved in several processes, including macrophage activation involved in immune response; positive regulation of defense response; and regulation of signal transduction. Located in several cellular components, including cytosol; extracellular space; and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

VAT1 (HGNC:16919): (vesicle amine transport 1) Synaptic vesicles are responsible for regulating the storage and release of neurotransmitters in the nerve terminal. The protein encoded by this gene is an abundant integral membrane protein of cholinergic synaptic vesicles and is thought to be involved in vesicular transport. It belongs to the quinone oxidoreductase subfamily of zinc-containing alcohol dehydrogenase proteins. [provided by RefSeq, Jul 2008]

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.16979924).
