Because multiple genes that encode proteins in the EGFR signaling pathway have been found to be mutated in lung adenocarcinomas, we specifically sought to identify potential gain-of-function mutations in gene families in this pathway, i.e. in ERBB1-4, PIK3CA, AKT1-3, FRAP1, RPS6K1-2, RAS (K-, N-, and H-), RAF (A-, B-, C-), MAP2K1-2, and MAPK-1-3.
Occasionally, there are imperfections, called mutations, in gene replication.
Spontaneous generation of PrPSc in inherited forms of disease is caused by mutations in gene coding for PrP (PRNP).
Mutations in gene families and single genes were related to tumor stage, and expression of chromatin modifiers correlated with survival.
Seven of these diseases, including muscular dystrophies, cardiomyopathies, lipodystrophies, and most intriguingly, Progeria, or premature aging, are caused by mutations in gene encoding the A-type lamins.
Mutations in gene SGCG accounted for 7 of the 94 cases (8%), suggesting that the size of the gene makes it vulnerable to large exonic deletions.
Myriad's test, called BRACAnalysis, detects mutations in genes called BRCA1 and BRCA2.
Research on variation in human hair colouration has shown that mutations in genes that are involved in the synthesis of melanin pigments are largely responsible.
Women who carry mutations in genes called BRCA are already known to have a substantially higher risk of breast cancer, at around 65%.
This includes women with relatives who have had ovarian cancer, women who have had breast cancer, and women with mutations in genes called BRCA1 and BRCA2 that indicate a high risk of breast and ovarian cancer.
Drayna, speaking at the annual meeting of the American Association for the Advancement of Science in Washington, recently discovered that mutations in genes called GNPTAB, GNPTG and NAGPA are more common in people who stutter than in non-stutterers.
