Genes affected

BIN1 (HGNC:1052): (bridging integrator 1) This gene encodes several isoforms of a nucleocytoplasmic adaptor protein, one of which was initially identified as a MYC-interacting protein with features of a tumor suppressor. Isoforms that are expressed in the central nervous system may be involved in synaptic vesicle endocytosis and may interact with dynamin, synaptojanin, endophilin, and clathrin. Isoforms that are expressed in muscle and ubiquitously expressed isoforms localize to the cytoplasm and nucleus and activate a caspase-independent apoptotic process. Studies in mouse suggest that this gene plays an important role in cardiac muscle development. Alternate splicing of the gene results in several transcript variants encoding different isoforms. Aberrant splice variants expressed in tumor cell lines have also been described. [provided by RefSeq, Mar 2016]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 239 of the BIN1 protein (p.Val239Ile). This variant is present in population databases (rs146573197, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with BIN1-related conditions. ClinVar contains an entry for this variant (Variation ID: 290879). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt BIN1 protein function with a positive predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: 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). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

The variant c.715G>A (p.Val239Ile) in the BIN1 gene is reported as uncertain in ClinVar (Variation ID: 290879) and in LOVD database v.3.0. This variant has not been reported in dbSNP, gnomAD, 1000 Genomes Project or ClinVar. There is no information on frequency in gnomAD or 1000 Genomes Project. The variant is reported with an estimated allele frequency of 0.0004 in 1000 Genomes Project, 0.0003077 in gnomAD exomes and 0.0004777 in gnomAD genomes with no homozygous individuals reported. The nucleotide position is moderately conserved across 35 mammalian species (GERP RS: 4.64). In silico analysis indicates that the variant might be damaging. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The V239I variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The V239I variant is observed in 63/126,240 (0.05%) alleles from individuals of European background (Lek et al., 2016). The V239I variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. In-silico analyses, including protein predictors and evolutionary conservation, support that this variant does not alter protein structure/function. Based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant. -
