The Institute of Medical Genetics and Genomics was created in 1997. It has grown over the years into a leading genetic centre in India. More than 7000 patients are counselled every year and about 20,000 tests are performed every year. The patients and samples are referred from all over India as well as our neighbouring countries.
The institute has fi ve sections (clinical, molecular, cytogenetic, biochemical and HLA and immunogenetics). The faculty consists of a good mix of clinical geneticists and PhD scientists, along with paramedical staff. The institute offers the comprehensive services for diagnosis, counselling, prenatal diagnosis and management of patients with genetic disorders.
The institute has been awarded the FICCI award for 2017 for preventive care in India. The institute is a member of the Undiagnosed Diseases Network International and has initiated the Indian – Undiagnosed Diseases Programme.
Clinical genetics
The Clinical Genetics Department has the diagnostic expertise for all genetic disorders and recently there has been an expansion of its services into genomics. The spectrum of patients seen at our centre are as follows:
Paediatrics:
- Children with malformations, intellectual disability, autism – protocoldriven evaluation
- Neuromuscular and neurogenetic disorders
- Metabolic disorders – both diagnosis and treatment using special dietary therapies, ERT
- Short stature – syndrome diagnosis, hormonal, skeletal dysplasias, MPS, etc.
- Thalassaemia, haemophilia and other blood disorders – the most experienced laboratory for prenatal diagnosis of haematological disorders in India.
Foetal medicine:
Prenatal diagnosis and counselling is provided for:
- Cases of a previous child with suspected genetic problems or another family member with genetic disorder
- Maternal serum screen-related issues (triple, quadruple and fi rst trimester tests, PIGF)
- Foetal congenital anomalies as seen on ultrasound, or growth problems or foetal demise
- Recurrent spontaneous miscarriages, or bad obstetric history, PGD
- Foetal autopsy is performed comprehensively – recommended in pregnancies terminated for antenatally diagnosed foetal malformations, skeletal dysplasia, intrauterine growth retardation (IUGR) and intrauterine demise (IUD)
Genetics in other related specialties:
- Neurology, dermatology, ophthalmology and ENT, cardiology, nephrology, gastroenterology, haematology, oncology, etc.
DrNB programme
At our institute there is a 3-year DrNB-super-specialty course in medical genetics started in 2014. Genetic fellows are involved in clinical genetic evaluation as well as with laboratory work.
They are provided training in clinical and metabolic genetics including evaluation of a suspected genetic disorder patient or family. Genetic counselling and treatment of genetic disorders remains the main focus of their training. They are also trained in laboratory work – to understand and also perform many molecular, cytogenetic and biochemical tests. Prenatal diagnosis and foetal medicine forms a major bulk of clinical genetics work, and fellows are comprehensively trained in the two fi elds in their DrNB training. Since the inception of the programme in 2014, three DrNB fellows have received a gold medal for their exemplary performance in the subject.
Research
Despite being a busy clinical and laboratory service for genetic tests, research fi nds an important place in the departmental activities. Many projects completed in the past have added new information on genetic disorders in India. The institute has a large number of publications (over 200) to its credit. Six research projects are ongoing while 13 research projects have been completed.
Laboratory services
The four laboratories (cytogenetics, molecular, biochemical and HLA genetics) function independently and are headed by expert PhD doctors. About 20,000 tests are carried out each year. Our molecular genetics laboratory has expanded its repertoire of tests to include next-generation sequencing including examination of fastq fi le for genomic data analysis. We have to our credit the identifi cation of many novel genes.
The molecular genetics lab performs ~630 types of tests (about 4500 tests per year). The tests range from PCR to advanced tests based on NGS. The cytogenetic section performs 40 types of tests (approximately 5000 tests per year), including chromosomal microarray analysis. The biochemical section performs ~125 types of tests (nearly 10,500 tests per year). Tests include enzyme assays on fi lter paper for lysosomal storage disorders, NBS, quantitative amino acids (UPLC), organic acid analysis (GC-MS), etc. The HLA section performs 40 types of tests (about 4100 tests per year). It also performs sophisticated tests such as donor-specifi c for single antigen as well as screening. It also perform test for relationship to check for relationship of subjects coming for transplantations. All the labs are most experienced in prenatal diagnostics in the country – prenatal samples (AF/CVS/Cord blood) are processed in the most precise, clean and timely manner, with results obtained between 2 day to 14 days. Sample types and requirements (other than prenatal samples):
- Molecular studies (DNA-based or gene studies): 3–4 ml blood in EDTA vial
- Cytogenetic studies: For karyotyping and FISH studies – 3–4 ml blood in heparin vial. For chromosomal microarray analysis – 3–4 ml blood in EDTA vial. To contact us for cancer cytogenetic testing.
- Biochemical genetics and HLA tests – as there are many tests, therefore it is best to enquire from lab before sending samples
For all tests, an informed consent form is required, along with appropriate clinical history and indication for test
For prenatal samples, laboratory should be informed in advance regarding sample shipment and requirements
At the Institute of Medical Genetics and Genomics, we are a group that is continuously striving for excellence in counselling, management, testing and prenatal diagnosis of genetic disorders. We are committed to compassionate patient care, accurate and timely performance of tests, and generating new knowledge in the fi eld of genetic disorders in India.
