GeneDx	RCV000438106	SCV000534464	benign	not specified	2016-12-27	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.
Personalized Diabetes Medicine Program, University of Maryland School of Medicine	RCV000445397	SCV000536988	benign	Monogenic diabetes	2018-10-12	criteria provided, single submitter	research	ACMG criteria: BP1 (disease caused by truncating variants), BA1 (1.9% in gnomAD African), BS2 (6 homozygotes in gnomAD African), BP4 (7 predictors + REVEL 0.039)= benign

Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV000438106	SCV000864097	benign	not specified	2017-02-06	criteria provided, single submitter	clinical testing	Variant summary: The ALMS1 c.10269G>C (p.Lys3423Asn, alternative name c.10275G>C) variant involves the alteration of a non-conserved nucleotide and is predicted to be benign by 3/5 in silico tools. This variant was found in 211/120598 control chromosomes (including four homozygotes), predominantly observed in the African subpopulation at a frequency of 0.019804 (194/9796). This frequency is about 9 times the estimated maximal expected allele frequency of a pathogenic ALMS1 variant (0.0022361), suggesting this is likely a benign polymorphism found primarily in the populations of African origin. It has not, to our knowledge, been reported in affected individuals in literature. One clinical diagnostic laboratory has classified this variant as benign. Taken together this variant is classified as benign variant.
Clinical Genomics, Uppaluri K&H Personalized Medicine Clinic	RCV001084442	SCV002605264	likely benign	Alstrom syndrome		criteria provided, single submitter	research	Potent mutations in ALMS1 are associated with a rare condition called Alstrom syndrome. It can cause excessive eating, insulin resistance. However, no evidence is found to ascertain the role of rs34398445 in Alstrom syndrome yet.
Ambry Genetics	RCV002379015	SCV002692094	benign	Cardiovascular phenotype	2018-12-24	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.
