Phenylketonuria: No diet

If untreated, the metabolism of the diet in phenylalanine results in accumulation of the amino acid in body fluids with resultant, progressive, and mental retardation

Phenylketonuria: Dieting

The diet for Phenylketonuria, is one of the most strictest and severe ones

Patau Syndrome: Occurs

Patau syndrome is the least common but one of the most severe of the disorders.

Patau Syndrome: Did you know..?

Cardiac occurs in 80% of all cases that are born with Patau Syndrome

Polydactyly

Is a geneitc disorder which results in at least 5 fingers or/and toes. The mutation occurs in Chromosome 7. It is cause by one gene called GLI3. This disorder occurs in 1 of every 500 births. It will not physically or mentaly change the way a person thinks, just a sympton that gives in a extra or multiple finger or toe. This disorder can be treated surgically. People don't just get this by growing an extra fingure throughout age, they geneitcally get this when they are born. There are 2 types of Polydactyly, Isolated Post-axial Poldactyly, which is more common in African-Americans and Pre-axial Poldactyly which is more common for Asians. The difference between them is that Isolated post-axial seems to happen commonly on the small finger or small toe, and Pre-axial seems to happen more commonly on the large thumb or toe. Polydactyly is an Autosomal Dominant patter of inheritance. This means that this is NOT sex-linked.

Phenylketonuria

Phenylketonuria is a rare condition in which a baby is born and cannot functionally break down the amino acide called Phenylalanine. The age group that are affected is when they are born. One out of every 10,000 - 15,000 born babies have Phenylketonuria. Some of the Symptoms of Phenylketonuria are, Mental retardation, Tremors, Skin rashes, Jerking moves of the arms and legs, Head size is below average (small), Seizures, and Hyperactivity. This disorder is NOT Sex-Linked. Phenylketonuria has a treatment but no complete cure. The treatment is a diet that must be strictly followed, since the person who has Phenylketonuria is extremely low in phenylalanine. What the doctors recommend on someone who has Phenylketonuria is that they should do the Diet for the rest of their life, and avoid any products containing aspartame. The diet should mainly be any food that is phenylalanine free. This disorder seems to occur more to Americans. Both males and females are equally to get this disorder.

Patau Syndrome

Patau syndrome, (also known as Trisomy 13) is a genetic disorder, when a person has 3 copies of genetic material in chromosome 13. This disorder seems to happen in 1 out of every 10,000 babies. The baby usually dies withing about 4-8 weeks after birth. If the baby survives, it will suffer severe mental retardedness for the rest of his/her life. Some Symptom's that appear are, 1 eye (some are fused together), mental retardedness, cleft lip, seizures, hole/split in the iris, extra finger or toes, low set ears, missing skin, small eyes, small head, small lower jaw, and undecended testicle. By far, there is no treatment or no cure for this disorder since the baby will die eventually. Males are most likely to get this kind of disorder. This disorder is NOT sex linked. All races are can get this disorder equally.
