Genes affected
CRBN (HGNC:30185): (cereblon) This gene encodes a protein related to the Lon protease protein family. In rodents and other mammals this gene product is found in the cytoplasm localized with a calcium channel membrane protein, and is thought to play a role in brain development. Mutations in this gene are associated with autosomal recessive nonsyndromic cognitive disability. Multiple transcript variants encoding different isoforms have been found for this gene.

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.83).
BS1
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0118 (1797/152286) while in subpopulation SAS AF= 0.0307 (148/4828). AF 95% confidence interval is 0.0266. There are 33 homozygotes in gnomad4. There are 1053 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High Homozygotes in GnomAd4 at 33 AR gene
