Timely diagnosis of alpha mannosidosis is important as it can influence how well the individual does in the long-term as therapies should be initiated as soon as possible.
In young patients, the presence of hearing impairment and/or speech delay are the main signs that should prompt your doctor to look for additional symptoms1A.
Adolescent and older patients may have different signs and symptoms, and mental retardation and motor impairment might warrant further investigation1A.
In both younger and older patients, a definite diagnosis may involve testing for the presence of certain sugars in urine or blood serum, and genetic testing may be used to confirm suspicion1A.
Your doctor can provide you with further information and recommend the right tests should alpha mannosidosis be suspected in any individual.
Your doctor may also refer the individual to see a metabolic disease specialist and/or clinical geneticist, who are more familiar with this rare condition. These specialists can recommend the appropriate tests to carry out to confirm that a person has alpha mannosidosis. In some cases, genetic testing may be done. Alpha mannosidosis is caused by what is called a recessive gene2A. If an adult carrying the abnormal gene has a partner who is also a carrier, there will be a 25% chance with every pregnancy that the baby will inherit the defective gene from each parent and will suffer from the disease3A.
There is a two of three chance that unaffected brothers and sisters of those affected by alpha mannosidosis will be carriers of the disease, but normal otherwise. However, since the disease is so rare, the chance of having a partner who is another carrier is very slight, unless the individuals belong to the same family3A.
