Article Synopsis
- Researchers studied mutations in a gene that affects a key protein involved in cell signaling, which is linked to severe health issues like impaired immunity in patients.
- The mutations were found to disrupt normal cell behavior by promoting excessive cell growth and responses to immune signals, specifically T cell receptor stimulation.
- The mutant protein was shown to interfere with a regulatory protein, leading to heightened activity of important signaling pathways that contribute to cell growth and survival.
SCY1-like protein 2 (SCYL2) is a member of the SCY1-like pseudokinase family which regulates secretory protein trafficking. It plays a crucial role in the nervous system by suppressing excitotoxicity in the developing brain. Scyl2 knockout mice have excess prenatal mortality and survivors show severe neurological dysfunction.

- Prenatal exome sequencing (pES) is increasingly used to diagnose fetuses with structural defects, identifying additional conditions in about 30% who have normal chromosomal microarray analysis (CMA).
- A study categorized prenatal phenotypes for fetuses with pathogenic variants, finding typical features in 67.9% of cases, while uncommon or unreported features complicated some interpretations.
- Recommendations include standardizing prenatal feature descriptions, enhancing follow-up practices, and collecting larger datasets to improve pES analysis.
The autosomal dominant Okur-Chung neurodevelopmental syndrome (OCNDS: OMIM #617062) is a rare neurodevelopmental disorder first described in 2016. Features include developmental delay (DD), intellectual disability (ID), behavioral problems, hypotonia, language deficits, congenital heart abnormalities, and non-specific dysmorphic facial features. OCNDS is caused by heterozygous pathogenic variants in CSNK2A1 (OMIM *115440; NM_177559.
