GeneDx	RCV000117231	SCV000168820	benign	not specified	2013-10-22	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.

Illumina Laboratory Services, Illumina	RCV000340336	SCV000376706	benign	Maturity-onset diabetes of the young type 3	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.

Clinical Genomics, Uppaluri K&H Personalized Medicine Clinic	RCV002226670	SCV002505638	uncertain significance	Type 2 diabetes mellitus		criteria provided, single submitter	research	Mutations in HNF1A gene can predispose to MODY3. It is associated with both micro and macrovascular complications of diabetes, especially cardiovascular complications. Associated with glucosuria and response to sulfonylureas. However, the role of rs1169289 of the HNF1A gene in predisposition for diabetes is not certain and needs clinical evidence.
Clinical Genomics, Uppaluri K&H Personalized Medicine Clinic	RCV002336253	SCV002605551	likely benign	Maturity onset diabetes mellitus in young		criteria provided, single submitter	research	Mutations in HNF1A gene can predispose to MODY3. It is associated with both micro and macrovascular complications of diabetes, especially cardiovascular complications. Associated with glucosuria. May respond well to sulfonylureas. Sufficient evidence is found to confer the association of this particular variant rs1169289 with MODY3.
Ambry Genetics	RCV002336253	SCV002644359	benign	Maturity onset diabetes mellitus in young	2014-12-08	criteria provided, single submitter	clinical testing	This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.

Genetic Services Laboratory, University of Chicago	RCV000117231	SCV000151404	likely benign	not specified		no assertion criteria provided	clinical testing	Likely benign based on allele frequency in 1000 Genomes Project or ESP global frequency and its presence in a patient with a rare or unrelated disease phenotype. NOT Sanger confirmed.
