Genetic study links defects in sugar digestion to irritable bowel syndrome
Sucrase-isomaltase (SI) is an intestinal enzyme critical for the digestion of dietary carbohydrates, particularly sucrose and starch. Previous studies from the Gastrointestinal Genetics team at CIC bioGUNE—BRTA and LUM ...

Genetic risk factor for Crohn's disease influences natural microbiome changes during pregnancy, mouse study finds
Pregnancy is accompanied by profound changes in the body. Among other things, these affect the energy metabolism and the immune system. But the gut microbiome, i.e., the composition of the microbial community in the gut, ...

Stem cells can tailor their role in gene therapy based on the underlying disease, study suggests
RCCS San Raffaele Scientific Institute in Milan researchers have discovered that hematopoietic stem cells (HSCs) adapt their lineage commitment during gene therapy based on the underlying genetic disease.

Study identifies a new disease-inducing mechanism for inflammatory bowel disease
Interleukin-10 (IL-10) is an anti-inflammatory protein that crucially controls intestinal immunity. Children with genetic defects in IL-10, or its receptors, suffer from a severe form of inflammatory bowel disease (IBD) that ...

Genetics, not lack of oxygen, causes cerebral palsy in quarter of cases: Study
The world's largest study of cerebral palsy (CP) genetics has discovered genetic defects are most likely responsible for more than a quarter of cases in Chinese children, rather than a lack of oxygen at birth as previously ...

Male infertility genetic study improves molecular diagnostics and personalized management of patients
Approximately one in seven couples face difficulties conceiving a child naturally. Half of these cases are due to male infertility—either caused by the complete absence or low number of mature sperm. In today's clinical ...

A genetic disorder is an illness caused by abnormalities in genes or chromosomes, especially a condition that is present from before birth. Most genetic disorders are quite rare and affect one person in every several thousands or millions.
A genetic disorder may or may not be a heritable disorder. Some genetic disorders are passed down from the parents' genes, but others are always or almost always caused by new mutations or changes to the DNA. In other cases, the same disease, such as some forms of cancer, may be caused by an inherited genetic condition in some people, by new mutations in other people, and by non-genetic causes in still other people.
Some types of recessive gene disorders confer an advantage in certain environments when only one copy of the gene is present.
