How is Kabuki Syndrome diagnosed?

Diagnosis of Kabuki syndrome typically involves a comprehensive evaluation encompassing clinical manifestations, physical examination, laboratory tests, imaging studies, and genetic testing. If concerns exist, early medical consultation is recommended. Detailed analyses are as follows:

1. Clinical manifestations: The physician will thoroughly review the patient's medical history, including growth and development status and the presence of distinctive facial features. If the patient presents characteristic facial features of Kabuki syndrome, such as elongated eyelids, outward turning of the lateral one-third of the lower eyelids, arched eyebrows, and a depressed nasal tip, this may suggest the presence of Kabuki syndrome.

2. Physical examination: A comprehensive physical examination will be conducted to observe whether the patient exhibits typical physical characteristics of Kabuki syndrome. The physician will carefully examine the patient's face, limbs, joints, spine, and other areas to assess for abnormalities.

3. Laboratory tests: Laboratory methods such as blood tests are used to evaluate the patient's hormone levels, metabolic status, and immune function. These tests help support the diagnosis of Kabuki syndrome and rule out other endocrine or immune system disorders that may cause similar symptoms.

4. Imaging studies: Imaging techniques such as ultrasound and MRI are used to evaluate the development of the patient's organs, especially to identify abnormalities in critical organs such as the heart and kidneys.

5. Genetic testing: DNA testing can determine whether there are gene mutations associated with Kabuki syndrome, such as mutations in the KMT2D or KDM6A genes.

Patients suspected of having Kabuki syndrome should seek timely medical evaluation and diagnosis to enable early implementation of appropriate interventions.
