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 />

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 />

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 />
