Variant summary
Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP4
The NM_001164507.2(NEB):c.11234G>T(p.Arg3745Leu) variant causes a missense change. The variant allele was found at a frequency of 0.0000341 in 1,612,978 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. R3745H) has been classified as Uncertain significance.

- -
In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Nemaline myopathy 2    Uncertain:2 
- -
This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 3745 of the NEB protein (p.Arg3745Leu). This variant is present in population databases (rs765379397, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with NEB-related conditions. ClinVar contains an entry for this variant (Variation ID: 465435). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0"). 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. -
