Illumina Laboratory Services, Illumina RCV000383039 SCV000409102 likely benign Juvenile polyposis/hereditary hemorrhagic telangiectasia syndrome 2017-04-27 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.

A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000213006 SCV000918227 benign not specified 2021-02-08 criteria provided, single submitter clinical testing Variant summary: SMAD4 c.1573A>G (p.Ile525Val) results in a conservative amino acid change located in the SMAD domain, Dwarfin-type (IPR001132) of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00059 in 254026 control chromosomes, predominantly at a frequency of 0.00098 within the Latino subpopulation in the gnomAD database. The observed variant frequency within Latino control individuals in the gnomAD database is approximately 490 fold of the estimated maximal expected allele frequency for a pathogenic variant in SMAD4 causing Juvenile Polyposis Syndrome phenotype (2e-06), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Latino origin. c.1573A>G has been reported in the literature in both non-cancer controls (example, Johnston_2012, Tram_2011) as well as in 2 patients with gastrointestinal polyposis (example, Ngeow_2013) and in others with cancer phenotypes and phenotypes not specified (example, Yorczyk_2015, Yurgelun_2015, Ring_2016, Maxwell_2016, Pelusi_2019, Tung_2015). The variant was also reported in somatic cancer tissues (example, Li_2015, Siroy_2015, Hamblin_2017). These report(s) do not provide unequivocal conclusions about association of the variant with Juvenile Polyposis Syndrome. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. 14 clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. The predominant consensus among all submitters is benign/likely benign (n=13). Based on the evidence outlined above and in alignment with the predominant consensus, the variant was classified as benign.

Myriad Genetics, Inc. RCV000383039 SCV004017788 likely benign Juvenile polyposis/hereditary hemorrhagic telangiectasia syndrome 2023-04-10 criteria provided, single submitter clinical testing This variant is considered likely benign. Homozygosity has been confirmed in one or more individuals. As homozygosity for pathogenic variants in this gene is generally assumed to result in embryonic lethality, this variant is unlikely to be pathogenic.
