Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000176426	SCV000540612	uncertain significance	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: Has been reported in 5 individuals with MKS, BBS, or NPHP (Davis 2011). All were heterozygotes only, except for one individual with BBS who also had a frameshift variant in this gene. Led to partial rescue of function in zebrafish knockdown studies and mislocalized protein in photoreceptors in retinal electroporation assays. Also identified in 1/356 control chromosomes. 0.9% freq in Eur chr in ExAC.

Illumina Laboratory Services, Illumina	RCV001135581	SCV001295370	likely benign	Asphyxiating thoracic dystrophy 4	2017-04-27	criteria provided, single submitter	clinical testing	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.
