New Genetic Screening Technologies (NIPT)
The search for prenatal detection of chromosomal anomalies has been ongoing since the 1960s. At the very beginning, maternal age was the screening parameter of choice, and Down syndrome the anomaly that was almost exclusively screened for. Since then things have, at least technically, changed enormously, even though Down syndrome is still the main focus of screening and in the minds of many patients the only diagnosis that they may confront. Structural chromosomal anomalies and monogenic diseases are still not focused on by current screening algorithms, nor by the education system or by society in general. With the clinical implementation of non-invasive prenatal testing (NIPT) in 2012, there has been a paradigm shift in prenatal screening. First trimester combined screening (FTCS) based on maternal age, fetal nuchal translucency thickness (NT) and the serum markers β-HCG and PAPP-A has a detection rate (DR) of 90–95%, a false positive rate of 2.5–5% and a PPV of 3.4 for the detection of trisomy 21. Included is the advantage that, if the results are abnormal, it could raise suspicion not only for the common trisomies, but also for early detectable fetal structural defects and other clinically relevant findings such as rare autosomal trisomies (RATs), triploidy, single gene disorders and copy number variants not detectable in a targeted NIPT approach. A disadvantage is the comparatively high false positive rate leading to invasive procedures.

Familial Mediterranean Fever
Familial Mediterranean fever is an inherited condition characterized by recurrent episodes of painful inflammation in the abdomen, chest, or joints. These episodes are often accompanied by fever and sometimes a rash or headache. Occasionally inflammation may occur in other parts of the body, such as the heart; the membrane surrounding the brain and spinal cord; and in males, the testicles. In about half of affected individuals, attacks are preceded by mild signs and symptoms known as a prodrome. Prodromal symptoms include mildly uncomfortable sensations in the area that will later become inflamed, or more general feelings of discomfort.

Canavan Disease
Canavan disease is a rare inherited disorder that damages the ability of nerve cells (neurons) in the brain to send and receive messages. This disease is one of a group of genetic disorders called leukodystrophies. Leukodystrophies disrupt the growth or maintenance of the myelin sheath, which is the covering that protects nerves and promotes the efficient transmission of nerve impulses.

Congenital Adrenal Hyperplasia
Congenital adrenal hyperplasia (CAH) due to 11-beta-hydroxylase deficiency is one of a group of disorders (collectively called congenital adrenal hyperplasia) that affect the adrenal glands. The adrenal glands are located on top of the kidneys and produce a variety of hormones that regulate many essential functions in the body. In people with CAH due to 11-beta-hydroxylase deficiency, the adrenal glands produce excess androgens, which are male sex hormones.

Pierre Robin Complex
The phenotype currently accepted as Pierre Robin syndrome/sequence/anomalad/complex (PR) is characterized by mandibular dysmorphology, glossoptosis, respiratory obstruction, and in some cases, cleft palate. A causative sequence of developmental events is hypothesized for PR, but few clear causal relationships between discovered genetic variants, dysregulated gene expression, precise cellular processes, pathogenesis, and PR-associated anomalies are documented.

DNA Damage and Multiple Myeloma
Multiple myeloma (MM) is an incurable plasma cell malignancy characterized by genomic instability. MM cells present various forms of genetic instability, including chromosomal instability, microsatellite instability, and base-pair alterations, as well as changes in chromosome number. The tumor microenvironment and an abnormal DNA repair function affect genetic instability in this disease. In addition, states of the tumor microenvironment itself, such as inflammation and hypoxia, influence the DNA damage response, which includes DNA repair mechanisms, cell cycle checkpoints, and apoptotic pathways. Unrepaired DNA damage in tumor cells has been shown to exacerbate genomic instability and aberrant features that enable MM progression and drug resistance.

Apert Syndrome
Apert syndrome is a genetic disorder characterized by skeletal abnormalities. A key feature of Apert syndrome is the premature closure of the bones of the skull (craniosynostosis). This early fusion prevents the skull from growing normally and affects the shape of the head and face. In addition, a varied number of fingers and toes are fused together (syndactyly).

Mind-Body Intervention and Diabetes
Mind–body intervention (MBI) refers to interventions like meditation, yoga, and qigong, which deal with both physical and mental well-being. MBI not only induces psychological changes, such as alleviation of depression, anxiety, and stress, but also physiological changes like parasympathetic activation, lower cortisol secretion, reduced inflammation, and aging rate delay, which are all risk factors for T2D. Notably, MBI has been reported to reduce blood glucose in patients with T2D.
