J Psychiatry Neurosci. From the periphery to centre stage: de novo single nucleotide variants play a key role in human genetic disease. Mutations result from errors during DNA or viral replication, mitosis, or meiosis or other types of damage to DNA (such as pyrimidine dimers caused by exposure to ultraviolet radiation), which then may undergo error-prone repair (especially microhomology-mediated end joining), cause an error during other forms of repair, or cause an error during replication (translesion synthesis). Approximately 25 percent of individuals who have Marfan syndrome, have the condition as a result of a new (de novo) mutation. MedlinePlus Genetics provides information about the effects of genetic variation on human health. 2020 Aug 21;11:938. doi: 10.3389/fgene.2020.00938. This is called a de novo mutation.

With the production of large quantities of next‐generation sequencing data from hundreds of genes involved in neurodevelopmental disorders such as schizophrenia, autism spectrum disorder, intellectual disability and epilepsy, de novo mutations have become a major focus of attention. The majority of such mutations arise in the paternal germline as a consequence of the greater opportunity for DNA replication errors to occur owing to the much higher number of cell divisions. At least 25% of cases are due to a new (de novo) mutation. However, despite this recent progress, our mechanistic understanding of these diseases is often incomplete. By using clinical exome sequencing, we identified six de novo pathogenic missense variants in SPOP in seven individuals with developmental delay and/or intellectual disability, facial dysmorphisms, and congenital anomalies.
