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.

Jul 20, 2021

The c.7G>A (p.G3S) alteration is located in exon 1 (coding exon 1) of the CRBN gene. This alteration results from a G to A substitution at nucleotide position 7, causing the glycine (G) at amino acid position 3 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
