Leopard syndrome is a rare genetic disorder. It is also known as Noonan syndrome. Leopard syndrome has symptoms like multiple lentigines. It is present at the time of birth or in early childhood. Other symptoms are spaced eyes (ocular hypertelorism), heart abnormality (pulmonary stenosis), short stature, distinctive facial features, abnormality of genitalia, and hearing loss.
The diagnosis of leopard syndrome is on the basis of clinical symptoms and genetic tests to know the mutation in PTPN11 gene.
Epidemiology
Leopard syndrome is found in different ethnic and racial groups. It is not limited to particular population. It is affected to both men and women. This disease cannot be recognized or diagnosed properly and can lead to difficulty to collect the accurate data.
Anatomy
Pathophysiology
The pathophysiology of leopard syndrome includes dysregulation of the cellular signaling pathways and effects on the different tissue and organ.
Dysregulated Cell Signaling: SHP-2 is a protein which is encoded by PTPN11 gene. It is a tyrosine phosphatase which modulates the signaling pathway included in the cellular growth, development, and differentiation. It regulates many receptors of tyrosine kinases like which are in the RAS-MAPK (Rat Sarcoma-Mitogen-Activated Protein Kinase) pathway.
RAS-MAPK Pathway Activation: Mutations in PTPN11 gene can lead to increased activity of SHP-2. This can lead to increase activation of RAS-MAPK pathway. The RAS-MAPK pathway is an important signaling cascade which controls the cell proliferation, differentiation, and survival. Dysregulation in this pathway can lead to abnormal cell growth and development in different tissues and organs.
Skin and Lentigines: The increased activity of RAS-MAPK pathway can lead to increased proliferation of melanocytes (pigment-producing cells) in skin. This excessive melanocyte proliferation can lead to development of the multiple lentigines. It is a dark spots or pigmented lesions on the skin.
Cardiac Abnormalities: Dysregulation in the signaling of RAS-MAPK pathway can affect the development and function of heart. The cardiac abnormalities linked with leopard syndrome like pulmonary stenosis.
Other Clinical Features: Dysregulation in the signaling pathway of RAS-MAPK can affect different tissues and organs in the body. It can lead to the different clinical symptoms seen in the leopard syndrome. These symptoms are like ocular hypertelorism, short stature, genital abnormalities, hearing loss, and other potential manifestations.
Etiology
The etiology of leopard syndrome is mainly connected to genetic mutations. Specifically, mutation in the PTPN11 gene is the common cause of the leopard syndrome.
The PTPN11 gene is located on the chromosome 12. It produces SHP-2 (Src-homology 2 domain-containing protein tyrosine phosphatase 2) protein. SHP-2 is important to regulate the cellular signaling pathway included in the cell growth, differentiation and development.
Mutation in the PTPN11 gene can lead to abnormal function and dysregulation of SHP-2 protein. These can lead to increased activity of SHP-2 and affect the RAS-MAPK signaling pathway.
The RAS-MAPK pathway is important in cellular signaling cascade included to control the different cellular processes like cell proliferation, differentiation, and survival. Dysregulation in the activation of RAS-MAPK pathway can develop leopard syndrome like multiple lentigines (dark spots on the skin), heart abnormalities (pulmonary stenosis), and other characteristic manifestations.
Most of the cases of leopard syndrome are caused by the de novo mutations. It is necessary to detect the specific genetic mutation in the PTPN11 gene. It can vary from different people who has leopard syndrome. The variability of the condition also may change.
Genetics
Prognostic Factors
The prognosis of LEOPARD syndrome may vary on the basis of many factors. It is a complex and rare genetic disease. The prognostic factors of leopard syndrome are like:
Specific PTPN11 Gene Mutation: The type and location of PTPN11 gene mutation can affect the severity and specificity of the symptoms of LEOPARD syndrome. Some mutations can be linked with more severe cardiac abnormalities and others may have mild symptoms.
Cardiac Abnormalities: The presence and severity of cardiac abnormality like pulmonary stenosis can affect prognosis. Regular cardiac monitoring and proper management are needed to cure the cardiac issue.
Hearing Loss: Hearing loss is a common symptoms of leopard syndrome. It can differ in the severity. Early detection and treatment can improve the long term result of hearing loss.
Complications and Comorbidities: The development of complications like heart related disease or other medical comorbidities can affect overall prognosis. Immediate recognition and management of complications are important.
Early Diagnosis and Treatment: Early diagnosis and treatment can be good to manage the symptoms and complications and improve the long term prognosis.
Family and Social Support: Strong family and social support can lead to positive effect on overall health and prognosis of the diseases.

Physical Examination
Skin Examination: Multiple lentigines is the main symptom of leopard syndrome. Healthcare provider will check for the distribution, number, and size of lentigines on different areas of the body like face, neck, trunk, and extremities.
Facial Assessment: Healthcare provider will assess the facial features like including ocular hypertelorism, a high-arched palate, and micrognathia specifically. They also see the overall appearance of the face.
Cardiac Evaluation: Healthcare provider will check the heart rhythm. Any abnormal sounds of heart can be the symptoms of leopard syndrome. Cardiac tests like an echocardiogram is performed to evaluate the structure and function of the heart.
Hearing Assessment: Healthcare provider will assess the hearing of patient by audiometry. They check for any impairment tin the hearing or responding to different sound frequency.
Growth and Development: The healthcare professional will measure the height and growth parameters for the growth retardation.
Skeletal Examination: Healthcare provider will assess the abnormalities in the skeletal like scoliosis or chest deformities. They observe the posture and skeletal alignment of patient.
Genital Examination: The healthcare provider will conduct a genital examination to check for any abnormalities of genitalia like cryptorchidism in men.
Neurological Assessment: The healthcare provider will check for any neurological problems like motor coordination and reflexes. They will assess for any signs of intellectual disabilities or development delays.
Other Organ Systems: Other organ systems is evaluated on the basis of clinical presentation of patient and symptoms or complications like endocrine abnormality, kidney disease or GI diseases.
Family History: A detailed family history is taken to know if the family has a history of similar genetic conditions.

Acuity of presentation
Leopard syndrome is a rare genetic condition with multiple lentigines. It can vary on acuity of presentation from mild to severe. Some patients may have symptoms like multiple lentigines in the early childhood. Other symptoms like cardiac abnormalities, hearing loss or short stature can also appear over the time. The acuity of presentation may be increase with the diagnosis. During the early childhood or later. Severe symptoms like pulmonary stenosis may be remain for short time after the birth or in infancy. It can lead to early diagnosis and medical treatment. The clinical symptoms of leopard syndrome can vary.
Differential Diagnoses
Noonan Syndrome (NS): Leopard syndrome is a subtype of Noonan syndrome. Both the diseases share many clinical symptoms. The presence of multiple lentigines is different from leopard syndrome.
Costello Syndrome: Costello syndrome have some clinical symptoms which are common to Noonan and LEOPARD syndrome, like heart abnormalities and developmental delays.
Cardiofaciocutaneous Syndrome (CFC): CFC syndrome is a rare genetic disorder which has the same symptoms like Noonan syndrome. It is caused by heart defects, distinctive facial features, and skin abnormalities.
Multiple Lentigines Syndrome (MLS): MLS is a rare genetic condition with multiple lentigines. Mutations in the RAF1 gene can lead to this disease.
Other Genetic Syndromes: Many other rare genetic syndromes may present with some features similar to LEOPARD syndrome.
