Some disorders are innate, i.e., present by birth, while others are acquired due to mutations in a particular gene.

There is a 50/50 chance of the child inheriting the disorder. Syndrome: When a group of signs and symptoms occur together and characterize a particular problem. Congenital Malformation: A condition that is present at birth. Multi-factorial Defects: Interaction of genes with other genes OR with environmental factors These are genetic diseases, and they can be very serious. Human Genetic Disorders. Many genetic disorders are caused by mutations in one or a few genes. Others are caused by chromosomal mutations. Some human genetic disorders are X-linked or Y-linked, which means the faulty gene is carried on these sex chromosomes Genetic disorder categories include: Chromosomal disorders Whole or part of a chromosome is missing or duplicated. These are large enough to be seen on a standard karyotype. 12. Evidence from scientific studies related to the patients' health problems is located, appraised and assimilated

X-linked hypophosphatemia (XLH) is an inherited disorder characterized by low levels of phosphate in the blood. Phosphate levels are low because phosphate is abnormally processed in the kidneys, which causes a loss of phosphate in the urine (phosphate wasting) and leads to soft, weak bones ().XLH is usually diagnosed in childhood The genes for sex-linked characters occur either in X- or Y or both XY chromosomes. Hence, sex-linked inheritances are of following types: 1) X- linked inheritance of traits (Diandric sex-linked): Genes for somatic characters are located on X-chromosome but not in Y-chromosome.It allows criss-cross inheritance KBG syndrome is a rare disorder that affects several body systems.

genetics of inherited diseases. For example, pedigrees can be analyzed to determine the mode of transmission for a genetic disease: (1) Dominance - whether the disease alleles are dominant or recessive; (2) Linkage - whether the disease alleles are X-linked (on the X chromsome) or autosoma This condition belongs to a class of genetic diseases called urea cycle disorders because they are caused by problems with a process in the body called the urea cycle. The urea cycle is a sequence of reactions that occurs in liver cells. This cycle breaks down excess nitrogen, which is made when protein is used by the body, to make a compound.
