NM_139343.3:c.461G>A
Variant summary
Our verdict is Likely pathogenic. The variant received 7 ACMG points: 7P and 0B. PM1PM2PP3_ModeratePP5
The NM_139343.3(BIN1):c.461G>A(p.Arg154Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000342 in 1,461,840 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R154W) has been classified as Uncertain significance.

Myopathy, centronuclear, 2 Pathogenic:2Uncertain:1
This variant is interpreted as a Likely pathogenic for Myopathy, centronuclear, 2 autosomal recessive. The following ACMG Tag(s) were applied: PM2 : Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. PS3 : Well-established functional studies show a deleterious effect (PMID:24755653). PP3 : Multiple lines of computational evidence support a deleterious effect on the gene or gene product. PM1 : Located in a mutational hot spot and/or critical and well-established functional domain (e.g., active site of an enzyme) without benign variation. -
This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 154 of the BIN1 protein (p.Arg154Gln). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with centronuclear myopathy (PMID: 20142620). ClinVar contains an entry for this variant (Variation ID: 8300). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt BIN1 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects BIN1 function (PMID: 24755653, 25262827). 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. -
