Genetic counselling, education, genetic services, and public policy<br />

privately such as in the USA, for instance.<br />

Since 2004, a screening program has been set up in a well-defined<br />

population of Tehran, Iran’s capital. Based on our experiments earned<br />

from referral/follow-up system within PHC, we designed 2 distinctive<br />

and comprehensive programs for the urban and rural areas.<br />

We therefore proposed following 3 phases:<br />

1-Mobilizing and organizing the community to active participation;<br />

2-Implementation,<br />

3-Assessment the program.<br />

Conclusion: As a general condition of Iran, population of 68 millions,<br />

population age distribution mean which is 23 years, high rate of consanguinity,<br />

strength of national PHC, general public demand, and the<br />

human rights may direct us to offer a national extraordinary health services<br />

including genomic services.<br />

This pilot survey may lead us to achieve valuable results; however,<br />

further studies are required to reach a comprehensive model.<br />

Switzerland.<br />

The new Swiss Federal Law of <strong>Human</strong> Genetic Analysis (LAGH),<br />

applicable from April <strong>2007</strong>, fixes the legal framework for prescribing<br />

and performing non-research genetic tests in humans. In the era of<br />

constantly-increasing genetic knowledge and of rapidly progressing<br />

laboratory techniques, the LAGH is designed to protect human dignity,<br />

prevent abuses and ensure a high standard of testing.<br />

We will focus principally on the medical application of the Law, which<br />

also encompasses testing in legal, workplace and insurance contexts<br />

including DNA profiling for investigating parentage and for identification<br />

purposes in civil and administrative proceedings.<br />

Non-directive genetic counselling and respect of the patient’s right to<br />

autodetermination is required and the conditions are described in detail<br />

in the text of the Law.<br />

Informed consent is required before performing any genetic testing,<br />

and must be obtained in writing before tests for presymptomatic, prenatal<br />

and “family planning” (reproductive choice) purposes.<br />

Prescription of genetic tests is restricted to medical doctors and, in prenatal<br />

or presymptomatic settings, to those with specific competence in<br />

genetic counselling.<br />

Licensing to perform molecular or cytogenetic testing is obligatory.<br />

The accompanying Ordinance on <strong>Human</strong> Genetic Analysis defines<br />

the criteria for the minimum acceptable standard of quality management,<br />

including the competence of the laboratory director and personnel,<br />

EQA and quality assurance requirements comparable to the ISO<br />

15189 standard.<br />

The obligations defined by the LAGH are closely based on pre-existing<br />

national and international standards and practices, yet Switzerland is<br />

one of the first countries in the World to transfer these into law.<br />

Medical genetics service is stationed at District Children Hospital. It<br />

works in close co-operation with the Department of Medical <strong>Genetics</strong><br />

of the MAPS, Municipal Centre of Medical <strong>Genetics</strong> etc. Genetic<br />

service realized neonatal screening for PKU and CH, cytogenetic investigations<br />

for making diagnosis of chromosomal pathology (2840<br />

samples), second trimester prenatal screening for congenital defects,<br />

double-test, (18000 pregnant women); confirmation of hereditary diagnosis,<br />

medical care, long term inpatient and outpatient care, dietary<br />

management, genetic counseling. 36589 of newborns(98,65%) were<br />

examined through neonatal screening. Five cases of PKU and five<br />

cases of CH were diagnosed. Cohort of children with PKU (23 cases)<br />

and with CH (46 cases) has special dietary and medicinal treatment.<br />

Ultrasound investigation was performed for pregnant women (25821of<br />

examinations). 225 of the fetuses were found to have congenital malformations.<br />

<strong>16</strong>0 of pregnancies were interrupted owing to congenital<br />

malformations or chromosomal diseases of the fetuses.<br />

P1363. Sequencing and MLPA under diagnostic rules<br />

Victoria, Australia.<br />

The field of molecular genetics is innovative and dynamic, resulting in<br />

continual upgrading or improvement of technology. Molecular genetic<br />

diagnostics therefore needs to be responsive to this to bring new or<br />

improved technology into clinical management of patients and families,<br />

but in the context of strict regulation and control. In Australia, the<br />

National Pathology Accreditation Advisory Council (NPAAC), the body<br />

responsible for setting guidelines and standards for medical laboratory<br />

accreditation, have released standards for validation of in-house<br />

developed assays for use in diagnostic testing. The detailed requirements<br />

include full documentation of the design phase, the production<br />

phase, the technical validation phase and the monitoring phase.<br />

The design phase includes literature review and /or peer consultation<br />

process to identify alternatives and the experience of other as well as<br />

the clinical usefulness of the proposed assay. The production phase<br />

includes conforming to safety principals for patients and laboratory<br />

staff as well as assessment of the analytical performance and the clinical<br />

performance of the assay. The technical validation phase includes<br />

assessment of the assay sensitivity and specificity, measurement of<br />

uncertainty if applicable and medically relevant criteria. The monitoring<br />

phase includes assessment of the assay performance in internal QC,<br />

external QAP or sample exchanges with other laboratories. The presentation<br />

will encapsulate the above phases of validation for molecular<br />

genetic testing in hereditary nonpolyposis colorectal cancer (HNPCC),<br />

using a capillary sequencing assay to detect unknown sequence<br />

changes and the MLPA assay (multiplex ligation-dependent probe amplification)<br />

to detect intragenic or whole gene deletion mutations.<br />

P1364. Myotonic Dystrophy in Yakuts (Russian Federation)<br />

Federation, 2 Yakutsk Science Center of Russian Academy of Medical Sciences<br />

and the Government of the RS(Y), Yakutsk, Russian Federation.<br />

In the Republic of Sakha (Yakutia) among Yakuts (430 thousand people)<br />

we have documented a high prevalence of DM1, that is is 21,3 per<br />

100 thousand.<br />

The purpose of this research was studying distribution among different<br />

ethinc groups, the clinical presentations of myotonic dystrophy and the<br />

distribution of the CTG-repeat in the indiginous populations of Yakutia.<br />

Two regions of accumulation of DM1 are established in the territories<br />

of Viluiskii and the Central group of uluses. In 35 Yakut families the<br />

classical form of myotonic dystrophy prevails (81,5 %), but we also<br />

encountered congenital and early childhood forms of the disease. The<br />

median age of patients with DM1 was 31,4±1,5 years, and the average<br />

age of onset was <strong>16</strong>,8±1,1 years. The most common clinical presentations<br />

were, progressive muscular weakness, cardiovascular and endocrinological<br />

symptoms. Family studies revealed clinical variability and<br />

anticipation. We analysed the distribution of CTG-repeat alleles in the<br />

normal Yakut population(Federova et al., 2003) in the two main ethnic<br />

groups groups (Viluiskii, Central, Northern Yakuts - <strong>19</strong>2 individuals).<br />

We found 18 different allelic variants from 5 up to 29 CTG-repeats. The<br />

most common alleles had 12 and 13 repeats (combined prevalence<br />

79 %). We found a low frequency (3-6 %) of unstable alleles with > <strong>19</strong><br />

CTG repeats.<br />

We suggest that one of the reasons for the accumulation of DM1 in<br />

the Yakut population is a founder effect of these unstable alleles. This<br />

needs to be confirmed in further studies. A method of preventive maintenance<br />

of DM1 in Yakuts is to provide effective medical-genetic consultation<br />

with prenatal DNA-diagnostics.<br />
