Description

For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with GAN-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Gln103*) in the GAN gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in GAN are known to be pathogenic (PMID: 12655563, 14718689, 23890932).
