Genes affected

ADRM1 (HGNC:15759): (ADRM1 26S proteasome ubiquitin receptor) This gene encodes a member of the adhesion regulating molecule 1 protein family. The encoded protein is a component of the proteasome where it acts as a ubiquitin receptor and recruits the deubiquitinating enzyme, ubiquitin carboxyl-terminal hydrolase L5. Increased levels of the encoded protein are associated with increased cell adhesion, which is likely an indirect effect of this intracellular protein. Dysregulation of this gene has been implicated in carcinogenesis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.14337909).

Ambry Genetics

Apr 13, 2022

The c.97C>A (p.L33M) alteration is located in exon 2 (coding exon 1) of the ADRM1 gene. This alteration results from a C to A substitution at nucleotide position 97, causing the leucine (L) at amino acid position 33 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
