The first child to survive bilateral renal agenesis (BRA), Abigail Rose Herrera Beutler, was born in July 2013 to US Congresswoman Jaime Herrera Beutler. [8] A few weeks before she was born, Dr. Jessica Bienstock, a professor of maternal–fetal medicine at Johns Hopkins Hospital, [ 9 ] administered a series of saline solution injections into ...
Trisomy 18, also known as Edwards syndrome, is a genetic disorder caused by the presence of a third copy of all or part of chromosome 18. [3] Many parts of the body are affected. [ 3 ] Babies are often born small and have heart defects . [ 3 ]
Uniparental inheritance of imprinted genes can also result in phenotypical anomalies. Although few imprinted genes have been identified, uniparental inheritance of an imprinted gene can result in the loss of gene function, which can lead to delayed development, intellectual disability, or other medical problems.

With de novo mutations and division errors, the relationship between the offspring's altered genes and gene inheritance from the parents is technically spurious. [13] These genetic errors can affect the mind as well as the body and can result in schizophrenia, [14] [15] autism, [11] bi-polar disorder, [16] and cognitive [17] disabilities.
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child. There are over 6,000 known genetic disorders in humans.
Ectodermal Dysplasia (ED) refers to a group of genetic disorders characterized by the abnormal development or function of two or more structures that originate from the ectoderm, the outer layer of an embryo. These structures include hair, teeth, nails, and sweat glands, all of which may develop abnormally in people with ED.
As with the vast majority of genetic disorders, there is no known cure to MICPCH. [citation needed] The following values seem to be aberrant in children with CASK gene defects: lactate, pyruvate, 2-ketoglutarate, adipic acid and suberic acid, which seems to backup the proposal that CASK affects mitochondrial function.

In genetics, a maternal effect occurs when the phenotype of an organism is determined by the genotype of its mother. [1] For example, if a mutation is maternal effect recessive, then a female homozygous for the mutation may appear phenotypically normal, however her offspring will show the mutant phenotype, even if they are heterozygous for the mutation.
