This report further expands the phenotypic spectrum to include the possibility of normal intelligence as corroborated by formal, longitudinal psycho-educational testing.The presence of two homologous low copy repeats either side of the deletion break-point suggests that non-allelic homologous recombination is the likely mechanism underlying this syndrome. Genetics
The microdeletion, around 1.6 million base pairs, in length and encompasses 5 known genes and 17 uncharacterised transcripts. These include transferrin receptor, choline-phosphate cytidylyltransferase A, RNF168, serine/threonine-protein kinase, nuclear cap-binding protein complex, melanotransferrin, DLG1 and D-beta-hydroxybutyrate dehydrogenase

Research
Research on the risk for developing schizophrenia in Ashkenazi Jews and other populations showed that 3q29 microdeletion syndrome leads to a significant higher rate of schizophrenia. In addition, a deletion at 3q29 was found to confer an increase to the odds of developing schizophrenia in a study of copy number variants and their effect on that disorder. References

Thunderstorm asthma (also referred to in the media as thunder fever or a pollen bomb) is the triggering of an asthma attack by environmental conditions directly caused by a local thunderstorm. It has been proposed that during a thunderstorm, pollen grains can absorb moisture and then burst into much smaller fragments with these fragments being easily dispersed by wind. While larger pollen grains are usually filtered by hairs in the nose, the smaller pollen fragments are able to pass through and enter the lungs, triggering the asthma attack. History
The phenomenon has been recognised for a significant period of time with a study of an event in Birmingham, England, noting the correlation between thunderstorms and hospitalisations. This fact that these were not isolated events and were part of an ongoing pattern of events is clearly documented in the review "Thunderstorm asthma, an overview of the evidence base". A significant impetus in the study of the phenomenon occurred after an event in 2016 in Melbourne, Australia. Since then there have been further reports of widespread thunderstorm asthma in Wagga Wagga, Australia; London, England; Naples, Italy; Atlanta, United States; and Ahvaz, Iran. The outbreak in Melbourne, in November 2016, that overwhelmed the ambulance system and some local hospitals, resulted in at least nine deaths. There was a similar incident in Kuwait in early December, 2016 with at least 5 deaths and many admissions to the ICU.
