Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP4_StrongBS1_Supporting

The NM_016302.4(CRBN):c.16G>C(p.Asp6His) variant causes a missense change. The variant allele was found at a frequency of 0.0000589 in 1,612,898 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D6E) has been classified as Uncertain significance.

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 was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.02789113).

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000582 (85/1460640) while in subpopulation SAS AF = 0.000313 (27/86178). AF 95% confidence interval is 0.000221. There are 1 homozygotes in GnomAdExome4. There are 50 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
