Investigators from the Thomas Jefferson University have presented a case report of a 27-year-old pregnant patient in whom cystic hygroma, extensive anasarca, bilateral pleural effusions, ascites, abnormally curved sacrum and hydrocephalus with parenchymal volume loss, among others were detected by prenatal imaging during pregnancy (onset was at about 21 weeks of gestation).

The CEP250 gene encodes centrosome-associated protein CEP250, involved in the formation of active centrosome components and cell cycle progression. CEP250 has been previously implicated in atypical Usher syndrome, which is characterized by early-onset hearing loss and mild retinitis pigmentosa.

Otosclerosis affects about 0.3% of population and it is among the most common cause of conductive hearing loss. Otosclerosis is highly familial, with positive family history reported in about 50% to 60% of cases. The disease is characterized by pathologic remodeling of the bone encasing the inner ear (otic capsule).

Amyotrophic lateral sclerosis (ALS) is the most frequent adult-onset motor neuron disease, and it is pathologically related with frontotemporal dementia (FTD). Genetic studies have identified C9ORF72 as a major genetic cause of ALS/FTD. Further genetic analyses and validation studies have identified some other genes associated with ALS risk, highlighting among them the NUP50 gene, which encodes nuclear pore complex protein Nup50.

Cell cycle-associated protein 1 (CAPRIN1) is an ubiquitously expressed protein, the levels of which are usually high in tissues with an elevated cell turnover; it is also abundant in the brain, where it regulates the transport and translation of synaptic protein mRNA.

Scientists have found a rare genetic variant carried by 1 in 3,000 people, which they say has a larger impact on the risk of developing type 2 diabetes than any other genetic defect identified to date.
