Genes affected

INA (HGNC:6057): (internexin neuronal intermediate filament protein alpha) Neurofilaments are type IV intermediate filament heteropolymers composed of light, medium, and heavy chains. Neurofilaments comprise the axoskeleton and they functionally maintain the neuronal caliber. They may also play a role in intracellular transport to axons and dendrites. This gene is a member of the intermediate filament family and is involved in the morphogenesis of neurons. [provided by RefSeq, Jun 2009]

NT5C2 (HGNC:8022): (5'-nucleotidase, cytosolic II) This gene encodes a hydrolase that serves as an important role in cellular purine metabolism by acting primarily on inosine 5'-monophosphate and other purine nucleotides. [provided by RefSeq, Oct 2011]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 1 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 2.1276 (below the threshold of 3.09). Trascript score misZ: 0.35672 (below the threshold of 3.09).

BP4

Computational evidence support a benign effect (MetaRNN=0.06045562).

BS2

High Homozygotes in GnomAdExome4 at 3 gene
