Uncertain significance, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaJan 12, 2018This 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. -
Uncertain significance, criteria provided, single submitterclinical testingARUP Laboratories, Molecular Genetics and Genomics, ARUP LaboratoriesSep 12, 2022The p.Leu429Pro variant (rs61735272) has not been reported in the medical literature. The p.Leu429Pro variant is listed in the Genome Aggregation Database (gnomAD) browser with an allele frequency of 0.17% in the non-Finnish European population (identified in 122 out of 73,780 chromosomes), and is classified as likely benign by multiple labs in ClinVar (Variant ID: 43969). The leucine at codon 429 is weakly conserved considering 11 species (Alamut software v2.10.0), but computational analyses predict conflicting effects of this variant on protein structure/function (SIFT: tolerated, PolyPhen2: benign, MutationTaster: disease causing). Based on the available information, the clinical significance of the p.Leu429Pro variant cannot be determined with certainty. -

Benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpDec 21, 2020Variant summary: RBM20 c.1286T>C (p.Leu429Pro) results in a non-conservative amino acid change located in the Matrin/U1-C-like C2H2-type zinc finger domain (IPR003604) 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 0.0012 in 151016 control chromosomes, predominantly at a frequency of 0.0021 within the Non-Finnish European subpopulation in the gnomAD database (v3.1), including 1 homozygote. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 45-fold of the estimated maximal expected allele frequency for a pathogenic variant in RBM20 causing Dilated Cardiomyopathy phenotype (4.7e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Non-Finnish European origin. To our knowledge, no occurrence of c.1286T>C in individuals affected with Dilated Cardiomyopathy and no experimental evidence demonstrating its impact on protein function have been reported. Ten clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Multiple laboratories reported the variant with conflicting assessments (i.e. 5 calling it likely benign and 5 classifying it as VUS). Based on the evidence outlined above, the variant was classified as benign. -

Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsDec 31, 2018This alteration is classified as likely 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. -
