Center for Undiagnosed Congenital Syndromes in Children

The Center for Undiagnosed Congenital Syndromes in Children is part of the Center of Rare Diseases Göttingen (ZSEG) and is organized jointly by the Institute of Human Genetics and the Department of Pediatrics at the UMG.

By combining our outstanding scientific and clinical expertise, we aim to establish a precise diagnosis in children with unclear congenital syndromes as early as possible and to determine the genetic cause of their condition.

An early and correct diagnosis is very important for the affected children and their families. It provides the basis on which statements about the course of the disease can be made and decisions on therapeutic approaches and further steps in the care of these children can be taken. It is also essential to answer pressing questions for the families, for example, regarding the risk of recurrence of specific syndromes.

A syndrome is a congenital condition characterized by several features occurring together. These features may either be present at birth or may become present during childhood or adolescence. They can involve different organ systems and may for example include malformations of the head, the face or the limbs, dysfunction or malformations of organs, short stature or developmental delay.

Most syndromes have a genetic basis, although we do not know for all syndromes by what genetic change they are caused.

Congenital syndromes are often clinically and genetically heterogeneous. Conditions that are caused by the same genetic change may present very differently and, vice versa, syndromes may look very similar although they have a different genetic cause. This makes them difficult to diagnose by genetic testing if one uses the conventional method where only single genes or multiple known disease genes are analyzed in a steplike process. And many patients show unspecific or overlapping symptoms that are difficult to attribute to a distinct known syndrome for a clinical diagnosis.

Research on rare syndromes

Many congenital syndromes are extremely rare and we do not yet know their genetic cause. Unravelling such diseases is one of our main research areas. Using next generation sequencing technology, we perform whole exome and whole genome sequencing to search thousands of genes or even the entire genetic material of a patient to find causative changes (mutations).

Our MutationMining (MM) team of scientists and clinical experts analyzes and interprets the data and looks for potentially causative variants. In a next step, we perform functional experiments to find out whether the effects that an identified mutation has on a cellular or molecular level may indeed explain the patient’s condition.

Clinic for Undiagnosed Congenital Syndromes in Children

Our clinic is held jointly by physicians from the Institute of Human Genetics and the Children’s Hospital. Clinical examination, diagnostic assessment and genetic counselling can thus be provided to the families at one visit. If needed, specialists from other departments will join the multidisciplinary team.

When we see a child at our clinic, the findings from the clinical examination and the information we gain from previous tests and medical records may allow us to attribute the symptoms to a distinct syndrome. In such cases, we will discuss with the family whether it is possible and helpful to confirm the diagnosis by a genetic test. If the clinical picture does not suggest a known syndrome, we may offer the family to participate in one of our specific scientific studies which we perform in third-party funded research projects, for example, on microcephaly, skeletal disorders, craniofacial malformations and others. In these research studies, we use the latest sequencing technology to identify the genetic causes of undiagnosed syndromes.
