Genes affected

ARIH1 (HGNC:689): (ariadne RBR E3 ubiquitin protein ligase 1) Enables enzyme binding activity; ubiquitin-protein transferase activity; and zinc ion binding activity. Involved in protein ubiquitination. Located in Lewy body; cytoplasm; and nuclear body. Colocalizes with cullin-RING ubiquitin ligase complex. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

This sequence change replaces glutamic acid, which is acidic and polar, with alanine, which is neutral and non-polar, at codon 15 of the ARIH1 protein (p.Glu15Ala). This variant is present in population databases (rs779981165, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with ARIH1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1488407). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
