Diagnosis
Diagnosis
When a baby is born with MSS, you notice very quickly that something isn’t right. Their physical appearance is different from that of most babies. From the start, the newborn often has trouble breathing and feeding is very difficult. It usually takes a few more days to weeks until MSS is diagnosed.
The doctor who determines the condition (the diagnosis) is called a clinical geneticist. Firstly, this doctor will look at the visible and noticeable symptoms of MSS. You can find these symptoms here. The clinical geneticist also looks at X-rays of the bones in the hands after which the doctor can usually confirm whether or not it is MSS.
Genetic Examination
To make absolutely sure the diagnosis is correct, the clinical geneticist will also examine the genetic material (DNA research). This is done by taking a small blood sample from the child. In the blood, the geneticist looks for a change (mutation) in a certain part of the genetic material. The gene that is responsible for MSS is called NFIX.
