Illumina Laboratory Services, Illumina	RCV001123632	SCV001282485	likely benign	Immunodeficiency 35	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 and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease.

Ambry Genetics	RCV004032249	SCV004973620	uncertain significance	Inborn genetic diseases	2023-10-13	criteria provided, single submitter	clinical testing	The c.1108C>T (p.R370W) alteration is located in exon 8 (coding exon 6) of the TYK2 gene. This alteration results from a C to T substitution at nucleotide position 1108, causing the arginine (R) at amino acid position 370 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
