Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the MYT1L gene is commonly pathogenic or not. These statistics are base on transcript: NM_001303052.2. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Transcription factor that plays a key role in neuronal differentiation by specifically repressing expression of non- neuronal genes during neuron differentiation. In contrast to other transcription repressors that inhibit specific lineages, mediates repression of multiple differentiation programs. Also represses expression of negative regulators of neurogenesis, such as members of the Notch signaling pathway, including HES1. The combination of three transcription factors, ASCL1, POU3F2/BRN2 and MYT1L, is sufficient to reprogram fibroblasts and other somatic cells into induced neuronal (iN) cells in vitro. Directly binds the 5'-AAGTT- 3' core motif present on the promoter of target genes and represses transcription by recruiting a multiprotein complex containing SIN3B. The 5'-AAGTT-3' core motif is absent from the promoter of neural genes. {ECO:0000250|UniProtKB:P97500}.
• Disease: DISEASE: Mental retardation, autosomal dominant 39 (MRD39) [MIM:616521]: A form of mental retardation, a disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. MRD39 patients show delayed psychomotor development and autistic features. {ECO:0000269|PubMed:23033978, ECO:0000269|PubMed:23160955}. Note=The disease is caused by mutations affecting the gene represented in this entry.
