How is monosomy diagnosed?

The condition is identified through karyotyping. When performed during prenatal testing, karyotyping can detect if the mother’s chromosomes have any genetic abnormalities. Your doctor may also order tests to look for the physical symptoms of Turner syndrome.

What does chromosome 18 tell us?

Individuals with this chromosome abnormality often have intellectual disability, an unusually small head (microcephaly), widely spaced eyes (hypertelorism), low-set ears, and speech problems.

What is chromosome 18q-syndrome?

General Discussion. Chromosome 18q- syndrome (also known as Chromosome 18, Monosomy 18q) is a rare chromosomal disorder in which there is deletion of part of the long arm (q) of chromosome 18. Associated symptoms and findings may vary greatly in range and severity from case to case. However, characteristic features include short stature;

What is monosomy 18p?

What is the meaning of 18q?

Chromosome 18q- syndrome (also known as Chromosome 18, Monosomy 18q) is a rare chromosomal disorder in which there is deletion of part of the long arm (q) of chromosome 18. Associated symptoms and findings may vary greatly in range and severity from case to case.

What does 18q21 mean in genetics?

For example, “18q21” refers to band 21 of the long arm of chromosome 18. Evidence suggests that individuals with characteristic features of the disorder have deletions from within band 18q21 (e.g., 18q21.3) or 18q22 (e.g., 18q22.2) that may extend to the end (or “terminal”) of chromosome 18q (qter).
