Genetic Disorders Profiles of topics
Albinism Disorder in melanin production resulting in little or no pigmentation in the hair, skin, and eyes. It varies in severity.
ALS - Amyotrophic Lateral Sclerosis Neurological disease that attacks nerve cells that control skeletal muscles.
AAA Syndrome Affected individuals have 2 or 3 of the following: achalasia, Addison disease, and alacrima
Anencephaly ● Defect in the closure of the neural tube during fetal development ● Baby is missing a major portion of the brain, skull, and scalp.
Angelman Syndrome Mental retardation, small head, seizures, and bouts of laughter not associated with happiness
Becker Muscular Dystrophy ● weakness in muscles of upper body happens faster ● wheelchair-bound between ages 25-30
Bloom’s Syndrome ●Higher risk of childhood cancer, chronic pulmonary disease and Type 2 diabetes ●smallish stature, sun-sensitive skin, & a bloated nose.
Hereditary Breast Cancer ●Occurs in men & women ●Formation of lump in breast or underarm ●Detected with mammogram
Brittle Bone Disease ● aka Osteogenesis Imperfecta ● Lethal to mild cases ● Results in fragile or misshapen bones
Canavan Disease ● Causes brain tissue degeneration so that parts of the brain cells don’t complete development and die. ● Most children die by age 10.
Celiac Disease ●Cannot digest gluten ●If undiagnosed, it leads to malnutrition, dehydration and severe diarrhea. ●Can cause abdominal bloating
Type 1 Diabetes ●Abnormally high blood sugar levels ●Occurs at any age ●Not usually caused by lifestyle
Down Syndrome Down Syndrome is a genetic disorder in which a person is born with extra genetic material that causes mental and physical developmental problems. Symptoms include flattened facial features and poor muscle tone.
Duchenne Muscular Dystrophy ● Causes fatigue and muscle weakness ● usually affected children are confined to wheelchairs by age 12
Edwards Syndrome Half of the babies with this syndrome die within the first week. Causes heart and kidney, craniofacial, and limb defects
Ehlers-Danlos Syndrome Symptoms include loose joints, skin that stretches easily, and easy bruising.
Epidermolysis Bullosa Inherited connective tissue disorder causing blisters, friction between layers of skin and skin fragility. Severity ranges from mild to lethal.
Fabry Disease Lack of an enzyme that helps break down lipids, which builds up in the eyes and kidneys.
Fish Odor Syndrome ● aka Trimethylaminuria ● Symptoms present from birth ● Smell comes out in urine, sweat and breath.
Fragile X Syndrome ● Low IQ ● Speech & language problems ● Physical challenges
Hemophilia A blood disorder in which blood does not properly clot, leading to complications. Spontaneous bleeding can occur. Common symptoms are bruises, swelling, pain, or tightness in joints, inability to stop bleeding from injuries.
Hermaphrodism/Intersex Intersex or hermaphrodism (old term) refers to a a group of conditions where there is a discrepancy between the external genitals and the internal genitals (ovaries and testes).
Hirschsprung’s Disease Part of the intestine lacks nerve cells that enable the person the ability to poop
Huntington’s Disease An inherited disease that causes breakdown of nerve cells in the brain. This has a large impact on a person’s ability to move, thinking and psychiatric disorders. Most people develop signs in their 30s or 40s.
Kleinfelter Syndrome Males who have XXY sex chromosomes
Leigh’s Disease Mitochondrial (metabolic) problem affects central nervous system Most children die before age 7, though some survive to 17
Marfan Syndrome A genetic disorder that affects the body’s connective tissue. Connective tissue holds all of the cells, tissues, and organs together. Some other symptoms can be life- threatening.
Neurofibromatosis Refers to several inherited conditions often causing people to develop tumors, particularly in the brain
Noonan Syndrome A genetic condition that causes unusual facial characteristics, heart defects, bleeding problems, and skeletal malformations.
Parkinson’s Disease Parkinson’s disease is a progressive degenerative disease of the nervous system that affects movement and cognitive ability. Symptoms include tremors, slowed movement, rigid muscles, speech impairment, impaired posture and balance.
Phenylketonuria Can develop mental retardation, eczema, seizures, motor and behavioral problems including self- mutilation.
Prader-Willi Syndrome Children with this syndrome usually become obese and show mental retardation. Some have severe emotional outbursts.
Polycystic Kidney Disease Growth of many cysts in the kidney No known cure
Parry-Romberg Syndrome ● Slow degeneration of the soft tissue and skin usually on the left side of the face ● Can cause seizures and facial pain
Sickle Cell Anemia Sickle Cell Anemia is a condition where blood cells take a crescent shape. They block blood flow in blood vessels of limbs and organs. This can cause pain, organ damage and even infection.
Tay Sachs Degenerative, fatal condition of the central nervous system. Children usually die by ages 3-4.
Thalassemia “Cooley’s Anemia” Blood disorder that can cause anemia, fatigue, enlarged spleen and jaundice
Treacher Collins Syndrome Condition that alters the development of bones and tissues in the face
Turner Syndrome ● Girls have one X chromosome instead of 2. ● May have broad chest, webbed necks, and do not show normal sexual development
Usher Syndrome Hearing loss and “tunnel vision” 3-6% of children who are deaf have Usher Syndrome
Werner Syndrome Normal growth through puberty then rapid aging including thinning and graying hair, diabetes, cataracts, and osteoporosis.
Williams Syndrome ● Learning and mental problems ● Distinctive facial features, cardiac and connective tissue problems
