Chromosome 15q Partial Deletion

Chromosome 15q partial deletion (pronunciation: kroh-muh-sohm fihf-teen-kew par-shuhl dee-lee-shuhn) is a rare genetic disorder that results from the deletion of genetic material from the long arm (q) of chromosome 15.

Etymology

The term derives from the Greek words "chroma" meaning color, "soma" meaning body (referring to the colored bodies seen in the cell nucleus), and "deletion" from the Latin "deletio" meaning to destroy or remove. The "15q" refers to the specific location of the deletion on the 15th chromosome, long arm (q).

This deletion can lead to a variety of medical and developmental problems, which can vary widely in severity and may include intellectual disability, delayed development, physical abnormalities, and behavioral problems.

Symptoms

Symptoms of Chromosome 15q partial deletion can vary widely, even among individuals in the same family. Common symptoms may include intellectual disability, delayed development, behavioral problems, and distinctive facial features.
