This list includes 19 Diseases that start with J, from “Jacobsen Syndrome” to “Juvenile Systemic Lupus Erythematosus”. These entries cover genetic disorders, infections, and juvenile-onset conditions, useful for quick reference and study.
Diseases that start with J are clinically recognized conditions whose names begin with the letter J. They range from eponymous syndromes like Jacobsen Syndrome to juvenile systemic lupus erythematosus.
Below you’ll find the table with Disease, Key symptoms, Causes & risk factors, and Typical treatments.
Disease: The official disease name, so you can spot the term quickly and match it to other resources or clinical notes.
Key symptoms: Concise list of the main signs you or a patient might show, useful for rapid recognition and initial triage.
Causes & risk factors: Primary causes and common risk factors are summarized so you understand likely origins and who is most at risk.
Typical treatments: Usual first-line treatment options and referral notes help you see next steps and when to seek specialist care.

Descriptions
Juvenile Idiopathic Arthritis
Chronic childhood arthritis treated with NSAIDs, DMARDs and physical therapy; see a pediatric rheumatologist for persistent symptoms or joint damage.
Juvenile Dermatomyositis
Treated with corticosteroids and immunosuppressants and physical therapy; pediatric rheumatology and dermatology referral for diagnosis and monitoring.
Juvenile Myoclonic Epilepsy
Often lifelong but usually controlled with antiepileptic drugs (valproate, levetiracetam); see neurology for management and safety advice.
Joubert Syndrome
Rare congenital brain malformation; management is supportive (therapies, respiratory care) and involves neurology, ophthalmology and genetics.
Jervell And Lange-Nielsen Syndrome
Treat with beta-blockers, sometimes implantable defibrillator and hearing rehabilitation; urgent cardiology and ENT/genetics referral.
Jacobsen Syndrome
Multisystem congenital disorder needing cardiac, hematology and developmental support; genetics referral for diagnosis and family counseling.
Job Syndrome (Hyper-IgE Syndrome)
Manage infections aggressively, skin care, sometimes prophylactic antibiotics; specialist immunology and genetic counseling recommended.
Junctional Epidermolysis Bullosa
Rare genetic blistering disorder; wound care, infection prevention, pain control and nutrition; dermatology and genetics follow-up.
Juvenile Nasopharyngeal Angiofibroma
Usually treated with surgical removal or preoperative embolization; evaluation and treatment by ENT/head and neck surgery.
Juvenile Polyposis Syndrome
Requires regular endoscopic surveillance and polypectomy; surgical removal if cancer risk high; genetics referral for family screening.
Juvenile Open-Angle Glaucoma
Managed with eye drops, laser or surgical procedures to lower pressure; urgent ophthalmology care to preserve vision.
Juvenile Huntington Disease
Early-onset form of Huntington disease; symptomatic treatments and multidisciplinary care; neurology and genetics involvement recommended.
Jeune Syndrome (Asphyxiating Thoracic Dystrophy)
Management focuses on respiratory support, sometimes surgical expansion of the chest, and long-term orthopedic/genetic care.
Jejunal Atresia
Surgical correction shortly after birth is required; neonatal surgical and intensive care referral.
Juvenile Nephronophthisis
Progressive kidney disease managed with supportive care, dialysis or transplant; referral to pediatric nephrology and genetics.
Jarcho-Levin Syndrome
Rare congenital skeletal disorder; supportive respiratory and orthopedic care and genetics counseling are needed.
Juvenile Systemic Lupus Erythematosus
Managed with immunosuppressants and steroids; pediatric rheumatology required for organ involvement and long-term monitoring.
Juvenile Paget Disease
Treated with bisphosphonates and orthopedic management; endocrinology/orthopedics and genetics referral advised.
Juvenile Granulomatous Arthritis (Blau Syndrome)
Managed with immunosuppressants and biologics; requires rheumatology and ophthalmology follow-up.
