MYT1

Chr 20

myelin transcription factor 1

Also known as: C20orf36, MTF1, MYTI, NZF2, PLPB1, ZC2H2C1, ZC2HC4A

The MYT1 protein is a zinc finger DNA-binding transcription factor that binds to promoter regions of central nervous system proteolipid protein genes and regulates oligodendrocyte development and myelin gene transcription. Mutations cause autosomal dominant intellectual disability with variable features that may include seizures, autism spectrum disorder, and developmental delays, typically with onset in early childhood. This gene is highly constrained against loss-of-function variants in the general population.

Clinical SummaryMYT1
Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 0.98). One damaged copy is likely sufficient to cause disease.
