    ...while it may be all well and good to gather data about genetics and do research, in the end, such research needs to benefit patients. In the case of Van Ravenswaaij, that means patients and their parents: she specializes in children who have rare chromosomal abnormalities. ...more.

My work

I graduated in medicine at the University of Leiden, the Netherlands (1986) and, after my paediatric internships, I started a PhD study on the surveillance of preterm newborns. My thesis was entitled "Heart rate variability: physiology and clinical applicability in very preterm infants". In 1992 I started a specialisation in clinical genetics in Nijmegen and became registered as a clinical geneticist (1997) and clinical cytogeneticist (2002).

My main interest has always been children with multiple congenital anomalies and chromosome disorders, including disorders of sexual differentiation. Together with Prof. Albert Schinzel and others, I have initiated a European project on rare chromosome disorders (www.ECARUCA.net).

I am also interested in new molecular cytogenetic techniques to find small chromosome aberrations in children with mental retardation and/or congenital anomalies. The development of the array CGH technique offers new research possibilities and these have led to many phenotype-genotype studies in chromosome disorders and to the discovery of the CHD7 gene involved in CHARGE syndrome.

In 2006 I moved to the University Medical Centre Groningen, where I have continued my two multi-disciplinary outpatient clinics (for rare chromosome disorders and for CHARGE syndrome) and my studies into these syndromes. I am also involved in a multi-disciplinary team for disorders of sexual differentiation and in pre-implantation genetic diagnosis. In 2008 I became an associate professor in clinical genetics and, in 2011, I was appointed to a chair in Clinical Dysmorphology at the University of Groningen.

My main focus is the identification of genetic causes for syndromes and congenital anomalies using state-of-the-art high resolution molecular techniques, implementing these techniques in routine diagnostics, and translating the results back to patients and their families. In November 2011, I was awarded a ZonMw grant (Eur 212,000) to investigate how intranasal insulin aids the development and behaviour of children with Phelan-McDermid syndrome.

Ongoing research projects

  • Clinical cytogenetics: Phenotype-genotype studies, interpretation of array CGH results, genetic causes of male infertility, international databases (ECARUCA)
  • Microcephaly: Finding genetic causes of microcephaly by whole-exome sequencing and by studies on extended, consanguineous families
  • SNP-haplotyping and whole-exome sequencing in familial syndromes
  • Chromosome 6 research : Parent-driven project on 6q deletions and duplications, aiming to make a detailed genotype-phenotype map. In this phenotype-genotype study we try to relate certain genetic deletions or duplications on chromosome 6q to clinical features (e.g. development, behaviour and health, MRI brain scan, heart ultrasound).
  • CHARGE syndrome and CHD7 gene : Clinical and embryological overlap between CHARGE syndrome and Kallmann syndrome, classification of congenital heart defects in CHARGE syndrome, and CHD7 sequencing in congenital heart defects, cranial nerve defects, hearing and swallowing in CHARGE syndrome, exome-sequencing in CHARGE syndrome patients without a CHD7 mutation, interpretation of CHD7 missense mutations.
  • Phelan-McDermid syndrome : Intranasal insulin and the development and behaviour of children with Phelan-McDermid syndrome.
  • Genetic screening in children with epilepsy: Early and broad genetic screening of children with epilepsy using targeted next-generation sequencing. Aiming to improve diagnosis and quality of care

Abnormal Neurological Development - Early Diagnosis and Intervention (ANDDI)

The ANDDI research programme will study early diagnosis and intervention in children with abnormal neurological development in a multidisciplinary setting and cover all aspects, including aetiology, pathogenesis, epigenetics, diagnostic applications, accurate phenotyping (dysmorphology, neuroradiology, orthopedagogy) and intervention (diet, medication, etc.). The programme is part of the BCN-Brain Institute and of the Graduate School Medical Sciences, Groningen. See also Genetic screening in children with epilepsy
Leaders: C.M.A. van Ravenswaaij-Arts and T.J. de Koning

Two national, multi-disciplinary outpatient clinics in the UMCG

  • Clinic for children with rare chromosomal disorders, in collaboration with Dept of Paediatrics. (See also Five genes per minute programme)
  • Clinic for children with CHARGE syndrome. This is an expert clinic in which many specialists are involved; clinical geneticists, ENT, paediatricians, (paediatric) endocrinologists, (paediatric) cardiologists, child psychiatrists, gynaecologists, and ophthalmologists.

Besides my work as a clinical geneticist, I am involved in a number of parent support groups (CHARGE, Wolf-Hirschhorn syndrome, European 11q, Rare chromosome disorders). I am also a member of the Quality Committee of the European Society of Human Genetics, and an associate editor of the European Journal of Medical Genetics.
