Review Status:criteria provided, single submitter
Collection Method:clinical testing

The YY1AP1 c.664C>T variant is predicted to result in premature protein termination (p.Gln222*). This variant was reported in the homozygous state in a patient with features of Grange syndrome (Guo et al 2017. PubMed ID: 27939641). This variant has not been reported in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. Nonsense variants in YY1AP1 are expected to be pathogenic. This variant is interpreted as likely pathogenic. -
