Jul 23, 2021

In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; In addition, in silico splice predictors suggest this variant may lead to abnormal gene splicing. However, in the absence of RNA/functional studies, the actual effect of this sequence change is unknown; Not observed at significant frequency in large population cohorts (Lek et al., 2016) -
