Worst hereditary conditions parent not to give
We can't blame all of life's misfortune on our parents, but the range of less-than-ideal physical issues we can pin on them run from the unfortunate to the downright deadly. Many diseases and conditions result from various factors, often including both the genes we inherit to the food we eat and the environment we live in. But here are some doozies you can blame, at least partly, on Mom and Dad: LiveScience
Super size fries and a heavy set of genes is a recipe for obesity. One scientific theory suggests the same genes that helped our ancestors survive famines are now working against people living in places where food is plentiful. Genes have been shown to be the cause of obesity disorders such as Bardet-Biedl syndrome and Prader-Willi syndrome. Many of today's bulging waistlines have only to do with eating too much of the wrong foods, however.
Although baldness is common in men, scientists don't understand much about why so little is going on up there. Genes do play a role, but your mom is not the only one at fault. Baldness is likely due to abnormalities in several genes from one or both parents. People with a rare type of permanent baldness called alopecia universalis, lose hair all over their bodies and carry defective 'hairless' genes.
Pimples plague about 85 percent of U.S. teens, and some adults struggle with acne, too. But scientists aren't certain about all the causes of acne. Likely culprits include overproduction of natural skin oils, dead skin cells, contact with greasy stuff, plus the buildup of bacteria, experts say. Stress and hormones play roles, too. It’s pure myth that greasy foods, chocolate or even dirty skin are to blame, according to the Mayo Clinic. All that said, they Mayo Clinic says: "If your parents had acne, you're likely to develop it, too."
Ten million men in the U.S. cannot distinguish red from green. Yet the disorder only affects less than 600,000 American women. Why? The genes for red and green receptors sit near each other on the X-chromosome. Men only have one X-chromosome, which they inherit from their mother. Meanwhile, women have two, and a normal gene can often balance out a defective one.
The cause of most breast cancers is still a mystery, however researches have discovered that mutations in particular genes, such as BRCA1 and BRCA2, cause some cancers. Women who inherit the mutation tend to get cancer early in life and in both breasts. Men with BRCA1 have an increased risk of prostate cancer, while BRCA2 increases the likelihood of cancers in the male breast, prostate, pancreas, and elsewhere.
A family history of heart disease, diabetes, stroke or high blood pressure isn't good for your heart. Children of parents with heart and blood vessel diseases are more likely to develop them too. Plus, a person with a congenital heart defect is slightly more likely to have a baby with a heart defect.
