Hypomagnesemia with Secondary Hypocalcemia
Hypomagnesemia with secondary hypocalcemia is an inherited condition caused by the body's inability to absorb and retain magnesium that is taken in through the diet. As a result, magnesium levels in the blood are severely low (hypomagnesemia).

Isovaleric Acidemia
Isovaleric acidemia is a rare disorder in which the body is unable to properly break down a particular protein building block (amino acid). The condition is classified as an organic acid disorder, which is a condition that leads to an abnormal buildup of particular acids known as organic acids. Abnormal levels of organic acids in the blood (organic acidemia), urine (organic aciduria), and tissues can be toxic and can cause serious health problems.

Helicobacter Heilmannii Sensu Lato
Helicobacter heilmannii sensu lato refers to a group of bacterial species within the Helicobacter genus. The Helicobacter genus consists of at least 40 species of spiral-shaped (also described as corkscrew-shaped) flagellated, Gram-negative bacteria of which the by far most prominent and well-known species is Helicobacter pylori (H. pylori). H. pylori is associated with the development of gastrointestinal tract diseases such as stomach inflammation, stomach ulcers, duodenal ulcers, stomach cancers that are not lymphomas, and various subtypes of extranodal marginal zone lymphomass, e.g. those of the stomach, small intestines, large intestines, and rectumn. H. pylori has also been associated with the development of bile duct cancer and has been associated with a wide range of other diseases although its role in the development of many of these other diseases requires further study. The H. heilmannii sensu lato species of bacteria take as part of their definition a similarity to H. pylori in being associated with the development of stomach inflammation, stomach ulcers, duodenal ulcers, stomach cancers that are not lymphomas, and extranodal marginal B cell lymphomas of the stomach. It is important to recognize and diagnose the association of H. heilmannii sensu lato with these upper gastrointestinal tract diseases, particularly extranodal marginal zone lymphoma of the stomach, because many of them have been successfully treated using antibiotic-based drug regimens directed against the instigating H. heilmannii sensu lato bacterial species.

Methylmalonic Acidemia with Homocystinuria
Methylmalonic acidemia with homocystinuria is an inherited disorder in which the body is unable to properly process protein building blocks (amino acids), certain fats (lipids), and a waxy fat-like substance called cholesterol.

Mutational Landscape of Autism Spectrum Disorder Brain Tissue
Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder of early childhood onset, characterized principally by socio-communicative impairments and certain restricted behavioural patterns, but also associated with other neuropsychiatric and medical conditions. Rare post-zygotic mutations in the brain are now known to contribute to several neurodevelopmental disorders, including autism spectrum disorder (ASD). However, due to the limited availability of brain tissue, most studies rely on estimates of mosaicism from peripheral samples.

De-novo disease-causing variants in CDH
The genetic etiology of congenital diaphragmatic hernia (CDH), a common and severe birth defect, is still incompletely understood. Chromosomal aneuploidies, copy number variations (CNVs), and variants in a large panel of CDH-associated genes, both de novo and inherited, have been described. Due to impaired reproductive fitness, especially of syndromic CDH patients, and still significant mortality rates, the contribution of de novo variants to the genetic background of CDH is assumed to be high. This assumption is supported by the relatively low recurrence rate among siblings. Advantages in high-throughput genome-wide genotyping and sequencing methods have recently facilitated the detection of de novo variants in CDH.

Neurohypophyseal Diabetes Insipidus
Neurohypophyseal diabetes insipidus is a disorder of water balance. The body normally balances fluid intake with the excretion of fluid in urine. However, people with neurohypophyseal diabetes insipidus produce too much urine (polyuria), which causes them to be excessively thirsty (polydipsia). Affected people need to urinate frequently, which can disrupt daily activities and sleep.
