Array-CGH (Komparativna genomska hibridizacija)<\/strong> je mikroarray-bazirani citogenetski test koji otkriva varijante broja kopija (CNV) \u2014 dobitke i gubitke DNK \u2014 u celom genomu na rezoluciji 50-100 kb (mnogo vi\u0161a od ~5-10 Mb rezolucije kariotipa). Preporu\u010duje se kao test prvog reda za neobja\u0161njeno razvojno ka\u0161njenje, intelektualnu ometenost, autizam i multiple kongenitalne anomalije. Ne detektuje uravnote\u017eene preure\u0111enja, ta\u010dkaste mutacije ili mozaicizam niskog nivoa. Izvje\u0161taj: 5-10 dana.<\/p>\n

Array CGH Nedir ?<\/strong>
\nArray CGH (Comparative Genomic Hybridization), genetik materyalin (DNA) kopya say\u0131s\u0131ndaki de\u011fi\u015fiklikleri tespit etmek i\u00e7in kullan\u0131lan bir molek\u00fcler sitogenetik teknolojisidir. Bu teknoloji, bir\u00e7ok genetik hastal\u0131\u011f\u0131n tan\u0131s\u0131nda ve ara\u015ft\u0131rmalar\u0131nda kullan\u0131lmaktad\u0131r.<\/p>\n

Array CGH, bir mikroarray platformu \u00fczerine yerle\u015ftirilmi\u015f DNA prob dizilerinin kullan\u0131lmas\u0131yla \u00e7al\u0131\u015f\u0131r. Normal bir \u00f6rnekle hasta bir \u00f6rne\u011fin DNA’s\u0131 kar\u015f\u0131la\u015ft\u0131r\u0131l\u0131r ve bu sayede kopya say\u0131s\u0131ndaki de\u011fi\u015fiklikler tespit edilir. Normal bir \u00f6rnekteki DNA prob dizileri ile hastal\u0131kl\u0131 \u00f6rnekteki DNA prob dizileri kar\u015f\u0131la\u015ft\u0131r\u0131l\u0131r ve kopya say\u0131s\u0131nda art\u0131\u015f veya azalma oldu\u011fu tespit edilirse bu bir genetik de\u011fi\u015fiklik veya mutasyona i\u015faret eder.<\/p>\n

Array CGH, kanser gibi bir\u00e7ok hastal\u0131\u011f\u0131n tan\u0131s\u0131nda ve tedavisinde kullan\u0131lmaktad\u0131r. \u00d6rne\u011fin, kanser h\u00fccrelerinde genetik de\u011fi\u015fiklikler s\u0131k\u00e7a g\u00f6r\u00fclmektedir ve bu de\u011fi\u015fiklikler, kanser h\u00fccrelerinin normal h\u00fccrelerden farkl\u0131la\u015fmas\u0131na neden olur. Array CGH, kanser h\u00fccrelerindeki bu genetik de\u011fi\u015fiklikleri tespit ederek, kanserin tan\u0131s\u0131nda ve tedavisinde \u00f6nemli bir ara\u00e7 olabilir.<\/p>\n

Array CGH ayr\u0131ca, kal\u0131tsal hastal\u0131klar\u0131n tan\u0131s\u0131nda da kullan\u0131l\u0131r. Kal\u0131tsal hastal\u0131klar\u0131n baz\u0131lar\u0131, genlerdeki kopya say\u0131s\u0131 de\u011fi\u015fikliklerinden kaynaklan\u0131r ve Array CGH, bu de\u011fi\u015fiklikleri tespit etmeye yard\u0131mc\u0131 olabilir.<\/p>\n

Array CGH’nin di\u011fer bir avantaj\u0131, bir\u00e7ok geni ayn\u0131 anda analiz edebilmesidir. B\u00f6ylece, bir\u00e7ok genetik de\u011fi\u015fikli\u011fin ayn\u0131 anda tespit edilmesi m\u00fcmk\u00fcn olur. Bununla birlikte, bu teknolojinin baz\u0131 s\u0131n\u0131rlamalar\u0131 da vard\u0131r. \u00d6rne\u011fin, bu teknoloji yaln\u0131zca kopya say\u0131s\u0131ndaki de\u011fi\u015fiklikleri tespit edebilir ve gen mutasyonlar\u0131n\u0131 veya epigenetik de\u011fi\u015fiklikleri tespit edemez.<\/p>\n
