After a diagnosis

The first few weeks.

A rare genetic diagnosis usually arrives as a short letter with a long name on it, and very little else. What follows is the orientation we wish someone had handed us: what to do first, who is actually able to help, and which of the things that feel urgent can wait a week.

We are a research organisation, not a patient-support charity. Nearly everything useful on this page was written by people who do this work full time, and the most valuable thing we can do is point at them clearly.

First steps

What the support organisations consistently advise

Drawn from the published guidance of NORD, Global Genes and GARD. None of it is our own clinical advice, and none of it replaces your care team.

Get a copy of the report, and keep it

Ask for the full genetic test report rather than a summary. It names the gene, the specific variant, and how the laboratory classified it. You will be asked for those details repeatedly, by people who can help, for years.

Ask for a genetic counsellor

A genetic counsellor exists to explain results, inheritance and options in plain language, and to help you think through decisions. If one was not offered, ask — it is a normal request, and the guidance from every organisation below leads with it.

Ask for a care coordinator

Rare disease means many specialists and a great deal of paperwork. A care coordinator or hospital social worker organises appointments and referrals so that you are not the only person holding the whole picture.

Find the disease-specific organisation

For most named genetic conditions there is at least one family organisation. They hold the practical knowledge no database has: which clinics know the condition, what other families found useful, and where the registries are. NORD and GARD can help you find yours.

Ask about a registry

In a condition with a few hundred known patients, research is only possible if families enter their information into a registry. It is also often the fastest way to be told when something changes.

Let the rest wait

You do not have to become an expert this month. The literature will still be there, and the decisions that matter are rarely the ones that feel most urgent in the first week.

A caution

Reading about a rare disease online

Two things are worth knowing before you start searching, and nobody tends to say them out loud.

Published descriptions skew severe. The first cases of any rare condition to be written up are usually the most severely affected, because those are the ones that reach a specialist and get published. As more people are diagnosed, the described range almost always widens. An early paper is not a forecast.
Be careful what you post. In a condition with a few hundred patients worldwide, a variant plus a couple of ordinary details can identify a specific child — even in a private group, and even with no name attached. Share the minimum necessary.

If the diagnosis is CASK

There is a page for the CASK-specific references — the clinical chapter, the family organisations, the registries.
