Sinaptopatías.

The comorbid diagnosis of ASD and ID requires that social communication be below what is expected for the general developmental level (Criterion E of DSM-5). The clinical differentiation between both entities in young children or those with severe disability is particularly complex, requiring a multidisciplinary approach and systematic phenotypic refinement.

Deep intronic mutations.

Massive exome sequencing, as the most cost-efficient strategy in the genetic diagnosis of monogenetic Mendelian diseases, has a limitation imposed by its own design: it does not include the sequencing of intronic regions. It is already possible to carry out massive sequencing of the entire genome, but nevertheless, bioinformatics technologies and scientific accumulation…

Pulling the rope. What to do when a diagnosis is not reached.

We are evaluating a child with a neurodevelopmental disorder in whom we suspect a genetic cause because they present suggestive findings (e.g., associated multiple congenital malformations). We performed an aCGH which was normal. We also performed a clinical exome (mendeliome) which did not provide information …
