В исследование, проведенное в формате случай-контроль, вошли 45 пациентов с иридофундальной колобомой в возрасте от 75 дней до 58 лет (в среднем 29,36 ± 14,4 года) и 45 здоровых лиц (средний возраст 35,23 ± 13,92 года). Офтальмологическое обследование включало биомикроскопию, фундоскопию и тонометрию. Генотипирование проводилось методом полимеразной цепной реакции с анализом полиморфизма длин рестрикционных фрагментов (ПЦР-ПДРФ).</p></sec><sec><title>Результаты</title><p>Результаты. У двух пациентов с иридофундальной колобомой был выявлен гетерозиготный генотип CT (+/-) SNP rs667773, а у остальных был гомозиготный генотип CC (-/-) дикого типа. У всех контрольных лиц был выявлен гомозиготный генотип CC (-/-) дикого типа. PAX6 SNP rs3026354 характеризовался CC (-/-) дикого типа гомозиготного генотипа у всех пациентов. Ни гетерозиготный CG (+/-), ни гомозиготный GG (+/+) генотипы не были зарегистрированы у пациентов и лиц контрольной группы. Паттерн генотипа SNP rs662702 был CC (-/-) дикого типа гомозиготным у всех пациентов и лиц контрольной группы. Частота генотипа CC составила 95,56%, а генотипа CT — 4,4 %, в то время как частота аллеля C составила 97,78%, а частота аллеля T — 2,22 % в rs667773 C&gt;T SNP, частота SNP rs3026354C&gt;G генотипа CC и аллеля C была 100 % как в популяции пациентов, так и в контрольной группе. Частота SNP rs 662702C&gt;T генотипа CC и C аллеля также была 100 % у пациентов и в контроле.</p></sec><sec><title>Заключение</title><p>Заключение. Повышенная частота CC генотипа с C аллелем была более распространена у пациентов с иридо-фундальной колобомой. Два гетерозиготных CT генотипа rs667773C&gt;T SNP были зарегистрированы у двух пациентов с иридо-фундальной колобомой.</p></sec></abstract><trans-abstract xml:lang="en"><p>Purpose of this study is to identify selected single nucleotide polymorphisms (SNP) of the PAX6 gene and to assess their correlation with congenital iridofundal colobomas and other congenital ocular anomalies.</p><sec><title>Material and methods</title><p>Material and methods. It was a case-control study done on 45 patients aged from 75 days to 58 years (mean age 29.36 ± 14.4 years) with irido-fundal coloboma and 45 healthy controls aged 35.23 ± 13.92 years. Ocular examination was done by using slit-lamp microscopy inspection, fundoscopy and intraocular pressure measurement. Genotyping was done by using the polymerase chain reaction — restriction fragment length polymorphism (PCR-RFLP) method.</p></sec><sec><title>Results</title><p>Results. Two irido — fundal coloboma patients showed CT (+/-) heterozygous genotype of rs667773 SNP and the rest were wild-type CC (-/-) homozygous genotype. All controls showed CC-/- wild-type homozygous genotype. PAX6 SNP rs3026354 showed CC (-/-) wild-type homozygous genotype condition in all patients. Neither CG (+/-) heterozygous nor homozygous GG (+/+) genotype was reported in patients and controls. SNP rs662702, genotype pattern was CC-/- wild type homozygous in all patients and controls. CC genotype frequency was 95.56 and CT genotype was 4.4% while C allele frequency was 97.78 and T allele frequency was 2.22 % in rs667773 C&gt;T SNP. rs3026354C&gt;G SNP had 100 % CC genotype and C allele frequency in both case and control populations. SNP rs 662702C&gt;T showed 100 % CC genotype and C allele frequency in the case and control respectively.</p></sec><sec><title>Conclusion</title><p>Conclusion. The elevated frequency of the CC genotype with C allele was more common in irido fundal patients. Two heterozygous CT genotype of rs667773C&gt;T SNP were reported in two irido-fundal coloboma patients.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>полиморфизм</kwd><kwd>мутация</kwd><kwd>гены</kwd><kwd>ПЦР</kwd><kwd>RFLP</kwd><kwd>SNP</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polymorphism</kwd><kwd>mutation</kwd><kwd>gene</kwd><kwd>polymerase chain reaction</kwd><kwd>restriction fragment length polymorphism</kwd><kwd>single-nucleotide polymorphism</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">исследование поддержано Департаментом медицинских исследований Министерства здравоохранения и благосостояния семьи, Нью-Дели, Индия</funding-statement><funding-statement xml:lang="en">This study was funded by Department of Health Research, Ministry of Health &amp; Family welfare, New Delhi, India</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Georgala PA, Carr CB, Price DJ.
