Previously undescribed phenotypic findings and novel ACTG1 gene pathogenic variants in Baraitser-Winter cerebrofrontofacial syndrome.

Baraitser-Winter cerebrofrontofacial syndrome is an autosomal dominant disease characterized by multiple congenital abnormalities and intellectual disability, which is caused by mutations in either the ACTB or ACTG1 genes. In this report, we described novel phenotypic findings in two Mexican patients with the disorder in whom two novel ACTG1 mutations (c.176A > G, p.
