Аннотация
Изучение количественных и качественных признаков с точки зрения генетической направленности невозможно без учета болезней или особенностей, сцепленных с полом. В настоящее время геномная селекция по половым хромосомам, проведенная методом полногеномного ассоциативного исследования, не была ключевым фактором для разработки специального кода и функциональной аннотации генов с учетом библиотек GO, KEGG и анализа ранее выявленных генов. Целью научно-практического исследования было создание программного кода для проведения GWAS по половым хромосомам свиней и поиск функционально значимых генов для объяснения связи «фенотип – генетика пола», которая в дальнейшем конкретизирует селекционный отбор свиней в нуклеус популяции и позволит заранее прогнозировать наследственные заболевания животных. В данной статье мы впервые провели GWA-анализ геномных оценок племенной ценности признака конверсии корма с учетом только половых хромосом (sGWAS). Структурная аннотация выявила 21 ген, расположенный на Х-хромосоме, и восемь генов – на Y-хромосоме, включая гомологичный участок XY. Проведенный кластерный анализ полученных генов обнаружил значимую взаимосвязь с коэффициентом конверсии корма у восьми из них: STS, DDX3X, PUDP, PNPLA4, DHRSX, GPR143, SHROOM2 и PRKX. Функциональная аннотация данных генов выявила их значительный вклад в биологические процессы организма, включая наследственные заболевания и специфичность сцепленных с полом.
