Non-syndromic cleft lip with or without palate (NSCL/P) is a prevalent birth defect that affects 1/500–1/1400 live births globally. The genetic basis of NSCL/P intricate and involves both environmental factors. In the past few years, various inheritance models have been proposed to elucidate underlying mechanisms NSCL/P. These range from simple monogenic more complex polygenic inheritance. Here...

Oligogenic inheritance implies a role for several genetic factors in disease etiology. We studied oligogenic inheritance in Parkinson's (PD) by assessing the potential burden of additional rare variants in established Mendelian genes and/or GBA, in individuals with and without a primary pathogenic genetic cause in two large independent cohorts totaling 7,900 PD cases and 6,166 controls. An exce...

AIM To develop a screening in order to determine the more common syndromic and non-syndromic genetic SNHL, considering epidemiological data, information and the development of new technologies; clinical implications and bioethical issues. MATERIALS AND METHODS We reviewed the literature in order to develop a screening that includes: history, patterns of inheritance, physical evaluation, labor...

OBJECTIVE To relate diverse aspects of genetics and its applications to concepts in the Glorious Qur'an and the ḥadīth. STUDY DESIGN The author compared passages from the Glorious Qur'an and ḥadīth with modern concepts in genetics, such as recessive inheritance, genetic counseling, genetic variation, cytoplasmic inheritance, sex chromosomes, genetics-environment interactions, gender determina...

INTRODUCTION Mendelian inheritance is based on the transmission of a single gene on a dominant, recessive or X-linked pattern. Discoveries on DNA structure, the genetic code, the genome and the observation that some characters and hereditary diseases do not follow classical mendelian inheritance have led researchers to define other patterns of transmission, referring particularly to multifactor...

MOTIVATION Recent studies on human disease have revealed that aberrant interaction between proteins probably underlies a substantial number of human genetic diseases. This suggests a need to investigate disease inheritance mode using interaction, and based on which to refresh our conceptual understanding of a series of properties regarding inheritance mode of human disease. RESULTS We observe...

Alzheimer’s disease is one of the least understood brain disorders. The genetic association of Alzheimer’s disease (AD) is an area that attracts the interest of neuroscientists since it is similar to other neurological illnesses but quite a complex disorder. It is considered to be a genetically dichotomous disease exhibiting two currently documented forms known as early onset familial cases tha...

Epigenetic variation describes heritable differences that are not attributable to changes in DNA sequence. There is the potential for pure epigenetic variation that occurs in the absence of any genetic change or for more complex situations that involve both genetic and epigenetic differences. Methylation of cytosine residues provides one mechanism for the inheritance of epigenetic information. ...

Genetic disorders of growth are numerous and include defects of the central nervous system, hypothalamus, pituitary, thyroid, skeleton and other glands, tissues or organs. These disorders are caused by genetic variations that interrupt different points of the hypothalamic-pituitary axis and other synthetic pathways that are required for growth. The resulting growth disorders can be classified b...
