Illumina Laboratory Services, Illumina	RCV000286952	SCV000348543	benign	Symmetrical dyschromatosis of extremities	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.

This variant is present in ClinVar (Variation ID:292766). Evolutionary conservation and computational predictive tools for this variant are limited or unavailable. This variant is an intronic variant; splice prediction tools suggest that this variant may not affect splicing. However, further studies are needed to understand its impact. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain.
