Illumina Laboratory Services, Illumina	RCV000388794	SCV000375948	benign	Scapuloperoneal spinal muscular atrophy	2018-01-12	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 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.

Illumina Laboratory Services, Illumina	RCV000340970	SCV000375953	uncertain significance	Charcot-Marie-Tooth disease axonal type 2C	2018-01-12	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.
GeneDx	RCV000434806	SCV000514979	likely benign	not specified	2016-02-26	criteria provided, single submitter	clinical testing	This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	RCV001812795	SCV002048222	uncertain significance	not provided	2021-02-24	criteria provided, single submitter	clinical testing	The TRPV4 c.1825-15C>G variant (rs200602134), to our knowledge, is not reported in the medical literature. The variant is reported in the ClinVar database (Variation ID: 307126) and is listed in the general population with an overall allele frequency of 0.02% (54/282,662 alleles) in the Genome Aggregation Database. This is an intronic variant in a weakly conserved nucleotide, and computational analyses (Alamut v.2.11) predict that this variant may impact splicing by slightly weakening the nearby canonical acceptor splice site. However, most pathogenic variants in TRPV4 are missense variants or in-frame deletion variants (Nilius 2013). Due to limited information, the clinical significance of the c.1825-15C>G variant is uncertain at this time. References: Nilius B and Voets T. The puzzle of TRPV4 channelopathies.
