Recent advances have made molecular genetic testing for several forms of deafness more widely available. Previous studies have examined the attitudes of the deaf towards genetic testing, including prenatal diagnosis. This study examines the attitudes of deaf college students towards universal newborn hearing screening, including molecular testing for… (More)
The genetic fitness of an individual is influenced by their phenotype, genotype and family and social structure of the population in which they live. It is likely that the fitness of deaf individuals was quite low in the Western European population during the Middle Ages. The establishment of residential schools for deaf individuals nearly 400 years ago… (More)
The authors report a rare case of multiple intracranial fetuses in fetu, fulfilling Willis' traditional criteria, which include an axial and appendicular skeleton with surrounding organized tissue. This case was ascertained from studies of a full-term female neonate who presented with ventriculomegaly. A CT scan showed intracranial calcifications that were… (More)
BACKGROUND Hereditary pancreatitis (HP) is a rare autosomal dominant disorder with variable expression and an overall lifetime penetrance of 80%. We hypothesised that (1) monozygotic twins within similar environments would develop the typical signs of HP at a similar age, and (2) if penetrance were due to modifier genes or environment, all twin pairs would… (More)
OBJECTIVE To analyze the presence of Joint Committee on Infant Hearing (JCIH) risk factors and co-occurring birth defects (CBDs) in children with unilateral hearing loss (UHL). DESIGN Retrospective review. SETTING Statewide registry of universal newborn hearing screen data for all children born in Virginia from 2002 through 2008. PATIENTS The study… (More)
PURPOSE Permanent hearing loss at birth or in early childhood is common and has many genetic and environmental causes. Advances in the identification and characterization of genetic forms, combined with the early identification of children through the implementation of state-based Early Hearing Detection and Intervention programs suggests the need for… (More)
Genetic hearing loss: the journey of discovery to destination – how close are we to therapy?
