What is Allports syndrome?
Alport syndrome is a genetic condition characterized by kidney disease, hearing loss, and eye abnormalities. People with Alport syndrome experience progressive loss of kidney function. Almost all affected individuals have blood in their urine (hematuria), which indicates abnormal functioning of the kidneys.
What is the life expectancy of someone with Alport syndrome?
Prognosis of Alport syndrome Most men with Alport syndrome reach end-stage kidney disease and kidney failure by their 40s or 50s, which can reduce lifespan if not managed with dialysis or a kidney transplant. Most women with Alport syndrome have a normal lifespan.
What causes nephrogenic diabetes insipidus?
The acquired form of nephrogenic diabetes insipidus can result from chronic kidney disease, certain medications (such as lithium), low levels of potassium in the blood (hypokalemia), high levels of calcium in the blood (hypercalcemia), or an obstruction of the urinary tract.
How do you test for nephrogenic diabetes insipidus?
Diagnosis of nephrogenic diabetes insipidus is based on tests of blood and urine. Drinking increased amounts of water helps prevent dehydration. To treat nephrogenic diabetes insipidus, people restrict salt in their diet and sometimes take drugs to reduce the amount of urine excreted.
Can diabetes insipidus go away?
There’s no cure for diabetes insipidus. But treatments can relieve your thirst and decrease your urine output and prevent dehydration.
How much water does a person with diabetes insipidus drink?
Treatment for cranial diabetes insipidus Your GP or endocrinologist (specialist in hormone conditions) may advise you to drink a certain amount of water every day, usually at least 2.5 litres.
What happens if diabetes insipidus is left untreated?
Without treatment, diabetes insipidus can cause dehydration and, eventually, coma due to concentration of salts in the blood, particularly sodium.
What does a high level of heterozygosity mean?
High heterozygosity means lots of genetic variability. Low heterozygosity means little genetic variability. Often, we will compare the observed level of heterozygosity to what we expect under Hardy-Weinberg equilibrium (HWE).
What happens to heterozygosity during genetic drift?
When a small population experiences genetic drift, there will be a drastic decrease in genetic diversity and thus fewer heterozygotes in the new population. Over time in such a small population, one allele’s frequency will increase while the other decreases. This leads to a loss of heterozygosity, or the number of heterozygotes in a population.
Do you subtract heterozygosity from the total?
If we want the heterozygosity, we just subtract that from the total. With just two alleles it isn’t as efficient to calculate the heterozygosity by the “one minus the homozygosity route”. Consider the case, though, of a locus with 6 alleles.
What are the side effects of excessive thirst?
You may even experience blurred vision and fatigue. These are symptoms of excessive thirst, which may signal a serious underlying medical condition. certain prescription medications, including lithium, diuretics, and certain antipsychotics
