Description

A variant that is classified as likely pathogenic has been identified in the TUBA1A gene in a born individual of unknown sex. The c.808G>A, p.(Ala270Thr) variant has been reported as a variant of unknown origin. This variant and associated phenotype was previously reported by Kumar et al. Hum Mol Genet, 2010 PMID: 20466733. HPO-standardized clinical features were: Agenesis of the corpus callosum (HP:0001274); Pachygyria (HP:0001302); Cerebellar vermis hypoplasia (HP:0001320); Hypoplasia of the brainstem (HP:0002365); Cerebellar hypoplasia (HP:0001321); Dysgenesis of the hippocampus (HP:0025101); Dilated fourth ventricle (HP:0002198)
