Illumina Laboratory Services, Illumina	RCV000261685	SCV000366889	uncertain significance	Asphyxiating thoracic dystrophy 3	2018-01-13	criteria provided, single submitter	clinical testing	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. 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, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.

Invitae	RCV001850599	SCV002174809	uncertain significance	Jeune thoracic dystrophy	2021-09-02	criteria provided, single submitter	clinical testing	This sequence change replaces aspartic acid with glycine at codon 4292 of the DYNC2H1 protein (p.Asp4292Gly). The aspartic acid residue is moderately conserved and there is a moderate physicochemical difference between aspartic acid and glycine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with DYNC2H1-related conditions. ClinVar contains an entry for this variant (Variation ID: 302130). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt DYNC2H1 protein function. 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.
