GeneDx RCV001537801 SCV000233802 benign not provided 2018-01-30 criteria provided, single submitter clinical testing This variant is associated with the following publications: (PMID: 32499652, 25652356)
Illumina Clinical Services Laboratory,Illumina RCV000273225 SCV000392386 benign Acromicric dysplasia 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 benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000181499 SCV000695527 likely benign not specified 2020-10-19 criteria provided, single submitter clinical testing Variant summary: FBN1 c.3890A>G (p.Glu1297Gly) results in a non-conservative amino acid change located in the EGF-like domain (IPR000742) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0012 in 251352 control chromosomes, predominantly at a frequency of 0.0085 within the Latino subpopulation in the gnomAD database, including 2 homozygotes. The observed variant frequency within Latino control individuals in the gnomAD database is approximately 75.6- fold the estimated maximal expected allele frequency for a pathogenic variant in FBN1 causing Aortopathy phenotype (0.00011), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Latino origin. c.3890A>G has been reported in the literature in individuals affected with Marfan syndrome and single-suture craniosynostosis (e.g. Baudhuin_2015, Clarke_2018). These reports do not provide unequivocal conclusions about association of the variant with Aortopathy. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Six other clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. They have cited the variant as uncertain significance (n=1) and benign/likely benign (n=5). Based on the evidence outlined above, the variant was classified as likely benign.
