Abstract

Four major characteristics (cryptophthalmos, syndactyly, genital anomalies and affected siblings) and eight minor characteristics (alterations of the nose, ears, larynx, oral clefts, umbilical hernia, renal agenesis, skeletal anomalies and mental retardation) have been defined for the diagnosis of Fraser syndrome. The generally accepted criterion for the diagnosis is at least the presence of 2 major and one minor characteristic, or one major and four minor characteristics. The etiology of the syndrome is autosomal recessive and siblings are frequently affected. We show the characteristics of the 7 cases of Fraser syndrome identified in the consecutive series of 1,405,374 liveborn infants and 9,042 stillborn children surveyed by the Spanish Collaborative Study of Congenital Malformations (ECEMC) between April 1976 and March 1997. The minimal estimated frequency of Fraser syndrome is 0.43 per 100,000 liveborn infants and 11.06 per 100,000 stillbirths. As has been shown in other case studies, we have observed a wide clinical expression of this syndrome. At present it is possible to prenatally detect some of the characteristics of Fraser syndrome through ultrasound examination of eyes, digits and kidneys. Four out of the 7 cases we...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.

Enzyme Evolution
