Rare Chromosome & Gene Disorder Guides

Below you will find our free Information Guides to specific chromosome and gene disorders, as well as guides translated into various languages. Do scroll down to the bottom of the ‘Chromosome Disorder Guides – English’ table to view guides and reports on a wide range of related general topics like DNA sequencing, deletions and microdeletions, inversions etc. Be sure to check back regularly as new and updated guides are added. Please note, we are a small charity with limited funding, and so are dependent on clinicians volunteering to help us write, verify, update and translate our guides. NB, please check the date of publication of translated guides since the most recent update might be waiting for a volunteer clinician to translate it from English.

To read how we research and produce the guides, please click here.

Please click View + to expand each list and select the guide related to the chromosome or gene disorder or general topic in which you are interested.
