It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease.

Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine	RCV000180351	SCV000538237	benign	not specified	2016-03-29	criteria provided, single submitter	clinical testing	Variant identified in a genome or exome case(s) and assessed due to predicted null impact of the variant or pathogenic assertions in the literature or databases. Disclaimer: This variant has not undergone full assessment. The following are preliminary notes: frequency in ExAC 2.8% in european population with (24 homozygotes). Also Benign in Clinvar (by GeneDx and Emory)

Broad Institute Rare Disease Group, Broad Institute	RCV001258271	SCV001435196	benign	Joubert syndrome 17		criteria provided, single submitter	research	The c.993C>T (p.Phe331=) variant in ADCK3 has been identified in a French and Algerian individual with ubiquinone deficiency with cerebellar ataxia (PMID: 18319074), but has also been identified in >4% of European (Finnish) chromosomes and 33 homozygotes by ExAC (http://gnomad.broadinstitute.org/). In vitro functional studies provide some evidence that the c.993C>T variant may not impact protein function (PMID: 18319074). However, these types of assays may not accurately represent biological function. In summary, this variant meets criteria to be classified as benign for autosomal recessive ubiquinone deficiency with cerebellar ataxia.
