reproductive medicine facilitate for the couples to choose the gender of their future child prior to pregnancy by using a method called “Preimplantation Genetic Diagnosis” (PGD). (2‚4‚5) (PGD) is a technique used to detect genetic and or chromosomal abnormalities in the embryo following fertilization in vitro at the eight-cell cleavage stage where one or two cells are biopsied and sent for genetic analysis. (2) Additionally‚ (PGD) can be performed to detect the sex of the embryo in order to prevent

* Introduction: In an increasing globalized world‚ the impact of scientific discoveries and application quickly transcends national boundaries through the rapid exchange of products and ideas. All scholars predict that Genetics will be the foremost science of the 21st century. Technologies and resources generated by the human genome project and other genomics research are already having a major impact on research across the life sciences. By genetic science the legislators and judges easily understand

research is to identify and study genes involved in human development. You have been asked to participate in this research study because you (or your child) have (or has) one or more developmental abnormalities and chromosomal abnormalities that have been present since birth. Such chromosomal abnormalities may disrupt the function of genes required for normal growth and development. By identifying these genes in people with specific birth defects‚ we hope to reach a greater understanding of how the

Introduction Phenylketonuria has been defined as a form of genetic abnormality that an individual acquires due to lack of PAH enzyme reduction that makes that individual unable to metabolize phenylalanine tyrosine. On the other hand‚ Down syndrome has been referred to a type of genetic condition that makes an individual to experience some sort of learning disability as well as different characteristic physical features. Down syndrome is also defined as a birth condition that is experienced by individuals

Spontaneous abortion is caused by chromosomal abnormalities‚ vascular diseases‚ diabetes‚ infections‚ uterus abnormalities and trauma among others. (Isabel 1992) On the other hand‚ induced abortions are caused by deliberate intervention. Induced abortions include both‚ those performed in accordance with legal sanctions‚ and those

Often times an IQ score less than 70 can be used to identity neurological dysfunction. Further test can determine whether a person has syndromic intellectual disabilities such as down syndrome‚ or a non-syndromic intellectual disability were abnormalities aren’t apparent (Kaufman‚ Ayub‚

Sonic hedgehog (SHH) plays an important role in patterning various embryonic identities. (Johnson et al.‚ 2014) Mutation in the sonic hedgehog enhancer leads to limb malformation in humans. There are 13 different point mutations and 10 duplications in humans involving the ZRS that have been shown to cause human malformation such as preaxial polydactyly‚ triphalangeal thumb and syndactyly. (VanderMeer and Ahituv‚ 2011) The role of the zone of polarizing activity control sequence (ZRS) is to produce

After the child is born there are many more indicators that doctors can look for including a wide neck‚ a receding or small lower jaw‚ and low-set ears (Mayo Clinic Staff‚ 2014). During the stage of puberty and beyond a doctor can look for abnormalities in growth‚ learning disabilities‚ or a failure to begin puberty. Looking for signs‚ likes these and the
