Which genetic condition should I choose for a biology project


Which genetic condition should I choose for a biology project?
Agammagoblulinemia Albinism Alcaptonuria Alzheimer's Charcot-marie-Tooth Cleft lip/palate Clubfoot Coffin Lowry syndrone Colorblindness Diabetes mellitus Down's syndrome Fragile X syndrome Galactosemia Glaucoma Hereditary deafness Hereditary cataract Hurler's syndrome Hypercholesterolemia Hypertension Maple syrup urine disease Marfan syndrome Muscular dystrophy Phenylketonuria Progeria Pyloric stenosis Spina bifida Thalassemia Trisomy 9 Trisomy 13 Trisomy 18 Turner syndrome Tuberous sclerosis Xeroderma pigmentosa These are the genetic conditions that I have to choose from, but I may choose a genetic condition not on the list as long as there is enough information for me to use to answer a couple of questions. These questions are about the affects of the condition, symptoms, treatment, inheritance pattern and a lot of other genetic information, genetic cause, diagnosis, cures or research for a cure, expected life span of a person w/ condition, frequency, and a punnet square to represent possible outcomes of offspring, etc. If anyone would like to know what the exact questions are, please feel free to post a comment letting me know, and I will try to post up the questions ASAP Which genetic conditions will allow me to find significant information? please give me a few conditions as I might now get my first choice, and please explain why you recommend it. Thank you

if you're going for an easy one i would say color blindness because i think it is fairly simple to understand how it is passed on, but for something more challenging that you might learn more from i would go with downs syndrome.

Hard to really say but if I was doing it I would chose Tay-Sachs disease (abbreviated TSD, also known as GM2 gangliosidosis or Hexosaminidase A deficiency). It 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. Research in the late 20th century demonstrated that Tay-Sachs disease is caused by a genetic mutation on the HEXA gene on chromosome 15. A large number of HEXA mutations have been discovered, and new ones are still being reported. These mutations reach significant frequencies in several populations. French Canadians of southeastern Quebec have a carrier frequency similar to Ashkenazi Jews, but they carry a different mutation. Many Cajuns of southern Louisiana carry the same mutation that is most common in Ashkenazi Jews. Most HEXA mutations are rare, and do not occur in genetically isolated populations. The disease can potentially occur from the inheritance of two unrelated mutations in the HEXA gene. Which is one of the reasons that it is so interesting because generally you need the same mutation. Until the 1970s and 80s, when the molecular genetics of the disease became known, the juvenile and adult forms of the disease were not always recognized as variants of TSD. Post-infantile Tay-Sachs was often mis-diagnosed as another neurological disorder, such as Friedreich ataxia.[5] Patients with LOTS frequently become full-time wheelchair users in adulthood, but many live full adult lives if psychiatric and physical difficulties are accommodated. Psychiatric symptoms and seizures can be controlled with medications. If you want to do it on this and need any help please let me know.
