Working together toward a cure

Publications by Others
Scientists' understanding of MYT1L is rapidly expanding, thanks to the dedication of a growing number of research teams around the world. The earliest publication describing MYT1L as a potential cause of intellectual disability and obesity appeared in 2011. Since then, multiple cohort studies and individual case reports have described people with MYT1L deletions, variants, and duplications. These reports have revealed both core characteristics of most people impacted by MYT1L differences and considerable diversity in the spectrum and severity of symptoms.
​
More recently, research utilizing mouse models and cell lines has advanced our understanding of MYT1L-related neurodevelopmental disorders. Research teams in the U.S., Korea and Germany have developed mouse models with loss-of-function of the MYT1L gene, effectively mirroring clinical features observed in patients with MYT1L mutations, and cell lines have enabled complementary experiments not possible in mice. Mouse and cell lines serve as a critical foundation for preclinical testing of both pharmacologic and targeted gene-based therapies for MYT1L Syndrome. ​​Below, we list both publications that have been reviewed and vetted by the scientific community, as well as a handful of newly written papers (pre-prints) that are still under review.

Cohort Studies in Humans
Recognition of MYT1L as a cause of developmental disability and obesity began with publications in the early 2010s of groups of patients ("cohorts") sharing similar characteristics, and all possessing deletions that included the MYT1L gene. A pivotal retrospective cohort study in 2022 carefully described and compared characteristics of individuals with MYT1L deletions, nonsense variants, missense variants, and duplications, and identified the frequency of common symptoms such as intellectual disability and other learning differences, autism spectrum disorder, obesity or overweight, and epilepsy across these subgroups.

2p25.3 Region, MYT1L and Obesity
The MYT1L Gene is located on chromosome 2 in a region called "2p25.3". While studies indicate that MYT1L haploinsufficiency alone often causes obesity, another gene located in the 2p25.3 region, TMEM18, has also been linked to obesity. Thus, obesity in individuals with deletions that include both MYT1L and TMEM18 may be linked to either or both genes.

Cell Line Studies
Cell line studies have been instrumental in elucidating the role of the MYT1L gene in neurodevelopmental disorders. Researchers have employed various cell models to investigate the consequences of MYT1L dysfunction.
Key findings from these studies include:
• Transcriptional Dysregulation: In a study published in PLOS Genetics, researchers created a human embryonic kidney (HEK) cell line with a null mutation in MYT1L using CRISPR-Cas9 technology. Gene expression profiling of this knockout cell line revealed that loss of MYT1L function leads to dysregulation of genes involved in neurodevelopmental processes. Notably, there was altered expression of genes associated with intellectual disability, suggesting that MYT1L plays a critical role in regulating neurodevelopmental gene networks.
• Neuronal Differentiation: Another study investigated the effects of MYT1L knockdown in human neural stem cells. The results indicated that reduced MYT1L expression impairs neuronal differentiation, highlighting its importance in maintaining neuronal identity and function. This study also identified a network of helix-loop-helix transcriptional regulators controlled by MYT1L, further emphasizing its role in neuronal development.
• Induced Neuronal (iN) Cells: MYT1L has been identified as a key factor in the direct reprogramming of fibroblasts into induced neuronal (iN) cells. The combination of three transcription factors—ASCL1, POU3F2/BRN2, and MYT1L—is sufficient to convert fibroblasts and other somatic cells into iN cells in vitro. MYT1L directly binds to specific DNA motifs on target gene promoters and represses transcription by recruiting a multiprotein complex containing SIN3B, thereby promoting neuronal identity.
These cell line studies have provided valuable insights into the molecular mechanisms by which MYT1L influences neuronal development and function.
