Genes affected

FBXO31 (HGNC:16510): (F-box protein 31) This gene is a member of the F-box family. Members are classified into three classes according to the substrate interaction domain, FBW for WD40 repeats, FBL for leucing-rich repeats, and FBXO for other domains. This protein, classified into the last category because of the lack of a recognizable substrate binding domain, has been proposed to be a component of the SCF ubiquitination complex. It is thought to bind and recruit substrate for ubiquitination and degradation. This protein may have a role in regulating the cell cycle as well as dendrite growth and neuronal migration. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BP6: Variant 16-87334218-G-A is Benign according to our data. Variant chr16-87334218-G-A is described in ClinVar as [Benign]. Clinvar id is 435179.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00925 (1409/152332) while in subpopulation AFR AF= 0.0323 (1345/41582). AF 95% confidence interval is 0.0309. There are 24 homozygotes in gnomad4. There are 667 alleles in male gnomad4 subpopulation. Median coverage is 34. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 24 AR gene
