Diseases
Granulomatous hypophysitis
Granulomatous hypophysitis: A rare disorder caused by the inflammation of the pituitary gland. It can occur as a result of other infections such as tuberculosis and sarcoidosis.

Granulosa cell tumor of the ovary: A rare type of ovarian tumor which can cause excess estrogen hormone production. The tumor is a low grade malignant tumor.
Graphite Pneumoconiosis
Graphite Pneumoconiosis: Lung damage caused by excessive inhalation of graphite. Cases are rare and severity can vary depending on the level of exposure.
Graves’ disease
Graves Disease: A form of hyperthyroidism where the thyroid gland produces too much thyroxine which results in various symptoms such as goiter, protruding eyes and skin disorders.
Gray platelet syndrome
Gray platelet syndrome: A rare inherited disease characterized by deficiency of alpha granule inside blood platelets which inhibits it's clotting ability.
Great vessels transposition
Transposition of the great vessels is a congenital heart defect in which the 2 major vessels that carry blood away from the heart -- the aorta and the pulmonary artery -- are switched (transposed).

Greig cephalopolysyndactyly syndrome
Greig Cephalopolysyndactyly Syndrome: A rare genetic disorder characterized by premature closing of skull bones and craniofacial abnormalities, finger and toe abnormalities.
Griscelli syndrome type 1
Griscelli syndrome type II: A rare genetic condition characterized by a partial lack of pigmentation in the eye, skin and hair, clumps of pigmentation in hair shafts, immunodeficiency and neurological symptoms.
Griscelli syndrome type 2
Griscelli syndrome is an inherited condition characterized by unusually light (Hypopigmented) skin and light silvery-gray hair starting in infancy. Researchers have identified three types of this disorder, which are distinguished by their genetic cause and pattern of signs and symptoms. Griscelli syndrome is a rare condition; its prevalence is unknown. Type 2 appears to be the most common of the three known types.
People with Griscelli syndrome type 2 (also known as "Partial albinism with immunodeficiency") have immune system abnormalities in addition to having hypopigmented skin and hair. Affected individuals are prone to recurrent infections. They also develop an immune condition called hemophagocytic lymphohistiocytosis (HLH), in which the immune system produces too many activated immune cells called T-lymphocytes and macrophages (histiocytes). Overactivity of these cells can damage organs and tissues throughout the body, causing life-threatening complications if the condition is untreated. People with Griscelli syndrome type 2 do not have the neurological abnormalities of type 1.
Griscelli syndrome type 3
Griscelli syndrome type III: A rare genetic condition characterized by a partial lack of pigmentation in the eye, skin and hair, clumps of pigmentation in hair shafts and immunodeficiency.
Grix Blankenship Peterson syndrome
Grix-Blankenship-Peterson syndrome: A very rare syndrome characterized mainly by mental retardation, bone defects and head and face abnormalities
Groenouw type I corneal dystrophy
Groenouw type I corneal dystrophy: A rare genetic condition affecting the corneas can resulting in impaired
Groll Hirschowitz syndrome
Groll-Hirschowitz syndrome: A rare genetic condition characterized by deafness, gastrointestinal abnormalities and neuropathy.
Grosse syndrome
Wiedemann Grosse Dibbern syndrome (medical condition): A syndrome which is characterised by the association of symptoms such as abnormal facies, short stature, and psychomotor retardation.
Group B strep disease in newborns
Group B streptococcus (GBS) is a bacterium that can be found in the digestive tract, urinary tract, and genital area of adults. Although GBS infection usually does not cause problems in healthy women before pregnancy, it can cause serious illness for the mother and baby during pregnancy and after delivery.
Grover’s disease
Grover's disease, or Transient Acantholytic Dyskeratosis (TAD), is a relatively common skin disease characterized by small red, bumpy spots
Growth and mental retardation- mandibulofacial dysostosis- microcephaly- and cleft palate
Growth delay - mental retardation - mandibulofacial dysostosis - microcephaly - cleft palate: A rare syndrome characterized by delayed growth, mental retardation, small head, cleft palate and facial and jaw anomaly.
Growth deficiency brachydactyly unusual facies
Growth hormone deficiency
Growth Hormone Deficiency (GHD) is a medical condition in which the body does not produce enough growth hormone (GH). Growth hormone, also called somatotropin, is a polypeptide hormone which stimulates growth and cell reproduction. HGH also refers to human growth hormone but this older abbreviation has begun to develop paradoxical connotations, particularly in relation to the peddling of medically unnecessary GH supplementation (so-called HGH quackery).
There are a variety of rare diseases which resemble GH deficiency, including the childhood growth failure, facial appearance, delayed bone age, and low IGF levels.
Growth mental deficiency syndrome of Myhre
Myhre syndrome is an extremely rare inherited disorder characterized by mental retardation, short stature, unusual facial features, and various bone (skeletal) abnormalities
Growth retardation alopecia pseudoanodontia optic
A rare condition characterized by retarded growth, alopecia, otpic atrophy and failure of teeth to erupt.
Growth retardation hydrocephaly lung hypoplasia
Growth retardation mental retardation phalangeal hypoplasia
A rare syndrome characterized mainly by retarded growth, mental retardation and underdeveloped digits.
Grubben de Cock Borghgraef syndrome
A very rare syndrome characterized mainly by poor muscle tone, developmental delay.
GTP cyclohydrolase deficiency
A rare metabolic disorder caused by an enzyme deficiency (GTP cyclohydrolase) which causes a harmful build up of phenylalanine in the blood.
Guanidinoacetate methyltransferase deficiency
A rare disorder of amino acid metabolism where glycine and proline are unable to be metabolized properly due to deficiency of the enzyme called guanidinoacetate methyltransferase.
