Variant summary
Our verdict is Likely benign. The variant received -3 ACMG points: 0P and 3B. BP4_ModerateBS1_Supporting
The NM_139343.3(BIN1):c.1439C>T(p.Thr480Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000229 in 1,613,396 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T480K) has been classified as Uncertain significance.

Inborn genetic diseases Uncertain:1
The c.1439C>T (p.T480M) alteration is located in exon 16 (coding exon 16) of the BIN1 gene. This alteration results from a C to T substitution at nucleotide position 1439, causing the threonine (T) at amino acid position 480 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
not provided Uncertain:1
In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Myopathy, centronuclear, 2 Uncertain:1
This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 480 of the BIN1 protein (p.Thr480Met). This variant is present in population databases (rs780918654, gnomAD 0.02%). 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: 461705). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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. -
