ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -4 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 2 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 2.2641 (below the threshold of 3.09). Trascript score misZ: 0.44683 (below the threshold of 3.09). GenCC associations: The gene is linked to complex neurodevelopmental disorder.

BP4

Computational evidence support a benign effect (MetaRNN=0.3649189).

BS2

High AC in GnomAdExome4 at 6 AD gene.
