Aneuploidi Kromosom Seks

Trisomi X

Triple X syndrome, also called trisomy X, is a genetic disorder that affects about 1 in 1,000 females. Females normally have two X chromosomes in all cells — one X chromosome from each parent. In triple X syndrome, a female has three X chromosomes. Many girls and women with triple X syndrome have no symptoms or only mild symptoms. In other cases, symptoms may be more pronounced — possibly including developmental delays and learning disabilities.

Monosomi X (Sindroma Turner)

Seoarang anak perempuan akan mewarisi masing-masing satu kromosm X dari kedua orangtuanya. Pada anak perempuan penderita  Turner syndrome, satu kopi kromosom X hilang atau rusak. Hal ini menyebabkan gangguan perkembangan janin dan masalah serupa setelah bayi dilahirkan. Misalnya, perawakan pendek, tidak terbentuk ovarium, atau gangguan belajat.
