Genes affected

FZR1 (HGNC:24824): (fizzy and cell division cycle 20 related 1) Predicted to enable anaphase-promoting complex binding activity and ubiquitin ligase activator activity. Involved in anaphase-promoting complex-dependent catabolic process; mitotic G2 DNA damage checkpoint signaling; and positive regulation of protein metabolic process. Located in nuclear membrane and nucleoplasm. Colocalizes with anaphase-promoting complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 5 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Gene score misZ: 3.6413 (above the threshold of 3.09). Trascript score misZ: 3.0028 (below the threshold of 3.09). GenCC associations: The gene is linked to developmental and epileptic encephalopathy 109.

BS2

High AC in GnomAdExome4 at 20 AD gene.
