Description

The TUBB2B c.602G>C variant is predicted to result in the amino acid substitution p.Cys201Ser. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.013% of alleles in individuals of European (Non-Finnish) descent in gnomAD. Alternative variant at the same codon p.Cys201Phe has been reported de-novo in an individual with tubulin-related dysgyria (Table 1, Stutterd et al. 2021. PubMed ID: 33604570). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
