De novo mutations in epileptic encephalopathies. Since many adults with disabilities have not undergone advanced genetic testing, it is likely that adults with this condition are underrecognized and underreported. Of note, phenotypic data on 11 individuals with a heterozygous de novo variant comes from the DECIPHER database. Funding for the project was provided by the Wellcome Trust. In most children with GRIN1-related disorders, the pathogenic GRIN1 variant occurred spontaneously (de novo) and was not inherited from either parent. (2) Some multigene panels may include genes not associated with the condition discussed in this GeneReview. Gorlin syndrome does not affect life expectancy. Congenital heart problems are associated with early mortality in Alagille syndrome, while severe liver dysfunction is associated with mortality later in life. Robinow Syndrome Prevention.
