Trisomy 16

Introduction

Overview

Overview

Trisomy 16 is a chromosomal abnormality in which there are three copies of chromosome 16 rather than two.[1] It is the most common chromosomal cause of miscarriage during the first trimester of pregnancy.

It is not possible for a child to be born with an extra copy of this chromosome present in all cells (called Full Trisomy 16).[2]

It is possible to be born with the mosaic form.[3][4]
