Retinitis Pigmentosa Symptoms

Retinitis pigmentosa is a group of related conditions associated with progressive degeneration of the light sensitive retina that lies at the back of the eye ball. This layer of photo sensitive cells with photoreceptors called rods and cones is normally associated with vision.

Tay-Sachs Disease Society and Culture

Tay-Sachs disease is a genetic disease that has been at the forefront of scientific research on inheritance patterns.

Tay-Sachs Disease Prevention

Tay-Sachs is a genetic disease that can be prevented through certain methods of mate selection, antenatal screening, and preimplantation genetic diagnosis.

Tay-Sachs Disease Diagnosis

The diagnosis of Tay-Sachs disease involves a consultation to gather details about the family and medical history of the patient, followed by a physical examination and blood tests to confirm the diagnosis.

Tay-Sachs Disease Pathophysiology

Tay-Sachs Disease is a progressive and fatal genetic condition that involves a complete deficiency of the hexosaminidase-A (HEXA) enzyme. This enzyme is needed in healthy individuals for the process of hydrolysis of GM2 ganglioside to occur. For individuals with Tay-Sachs disease that lack this enzyme, the fatty substance of GM2 ganglioside accumulates in the brain and leads to the symptoms of the disease.

Tay-Sachs Disease Symptoms

There are three different forms of Tay-Sachs disease, each of which is associated with its own set of distinctive symptoms.

What is Tay-Sachs Disease?

Tay-Sachs disease (abbreviated TSD, also known as GM2 gangliosidosis or Hexosaminidase A deficiency) is an autosomal recessive genetic disorder. In its most common variant known as infantile Tay-Sachs disease it presents with a relentless deterioration of mental and physical abilities which commences at 6 months of age and usually results in death by the age of four.

Sickle-Cell Disease History

It was not until 1910 that the first report of sickle cell disease was published in scientific literature.

Sickle Cell Disease Carriers

Sickle cell disease carriers, also sometimes referred to as people with sickle cell trait, are individuals that carry a single gene mutation for sickle cell disease.

Sickle-Cell Disease Treatment

When a child is diagnosed with sickle cell disease (SCD), they should be referred to a multidisciplinary specialist care team, experienced in the management of SCD. This team may be made up of a paediatrician, haematologist, clinical psychologist, pharmacist, physiotherapist, social worker and specialized nurse to help provide care for the various aspects of living with SCD on a chronic basis.

Sickle-Cell Disease Genetics

Sickle-cell disease is caused by a gene mutation that leads to the production of Sickle hemoglobin.

23 Nov 2009

Sickle-Cell Disease Pathophysiology

Sickle cell disease is an inherited genetic condition that involves defects in the shape and function of hemoglobin in the blood.

Sickle Cell Disease Diagnosis

The diagnosis of sickle cell disease usually involves a blood test that is analysed for defected genes or haemoglobin cells.

Sickle-Cell Disease Symptoms

Although sickle cell disease is present from birth, most patients do not begin to show signs of the condition until after the age of 4 to 6 months.

23 Nov 2009

Sickle-Cell Disease Classification

Sickle cell disease is a health condition that has the potential to lead to a number of complications, due to the altered shape of haemoglobin in the blood.

23 Nov 2009

What is Sickle-Cell Disease?

Sickle cell disease (SCD), also known as sick cell anaemia, encompasses a group of genetic disorders characterized by abnormal haemoglobin in red blood cells.
