Making a diagnosis for a genetic or rare disease can often be challenging. Healthcare professionals typically look at a person’s medical history, symptoms, physical exam, and laboratory test results in order to make a diagnosis. The following resources provide information relating to diagnosis and testing for this condition. If you have questions about getting a diagnosis, you should contact a healthcare professional.
If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

SLSN presents genetic and clinical overlap with other ciliopathies, in particular with isolated NPHP, Joubert syndrome related diseases (JSRD), mainly Joubert syndrome with oculorenal defect (JS-OR), Bardet-Biedl syndrome (BBS) and Alström syndrome (see these terms). Physical examination should consider the presence of the main clinical signs of JSRD (hypotonia, ataxia and breathing abnormalities in infants) and BBS (polydactyly and obesity). The phenotypic hallmark of JSRD is the presence on MRI of 'molar tooth sign' (a midbrain-hindbrain malformation). Other extrarenal signs to consider are nystagmus, psychomotor and learning delay, diabetes mellitus, deafness, hypogonadism, and/or scoliosis.
