Illumina Laboratory Services, Illumina	RCV000319939	SCV000371788	uncertain significance	Histiocytic medullary reticulosis	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.

Lurie Children's Hospital of Chicago	RCV000768066	SCV000898928	uncertain significance	Combined immunodeficiency with skin granulomas; Histiocytic medullary reticulosis; Severe combined immunodeficiency, autosomal recessive, T cell-negative, B cell-negative, NK cell-positive	2021-03-30	criteria provided, single submitter	clinical testing	RAG2 NM_000536.3 exon 2 p.Glu303Asp (c.909G>T): This variant has not been reported in the literature but is present in 0.1% (11/10360) of Ashkenazi Jewish alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/variant/11-36614810-C-A). This variant is present in ClinVar (Variation ID:304553). Evolutionary conservation and computational predictive tools for this variant are unclear; however, this variant is present in 3 species of fish. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain.
