(1969): multiple lentigines, electrocardiographic conduction abnormalities, ocular hypertelorism, pulmonic stenosis, abnormal genitalia, retardation of growth, and sensorineural deafness. Genetic Heterogeneity of LEOPARD Syndrome LEOPARD syndrome is a genetically heterogeneous disorder A number sign (#) is used with this entry because LEOPARD syndrome-1 (LPRD1) is caused by heterozygous mutation in the PTPN11 gene (176876) on chromosome 12q24. Mutation in the PTPN11 gene also causes Noonan syndrome-1 (NS1; 163950), a disorder with features overlapping those of LEOPARD syndrome GeneReviews ® [Interne t LEOPARD syndrome is a rare genetic condition that causes multiple congenital abnormalities, its name being an acronym for the major features of this disorder. Ocular hypertelorism is a characteristic of all forms of the LEOPARD syndrome. The lid fissures may be downward slanting. Combined with the inverted triangle facies, the appearance is similar to that of the Noonan syndrome (163950)

LEOPARD syndrome 1 (Concept Id: C4551484

Noonan syndrome with multiple lentigines (formerly called LEOPARD syndrome) is a condition that affects many areas of the body. As the condition name suggests, Noonan syndrome with multiple lentigines is very similar to a condition called Noonan syndrome, and it can be difficult to tell the two disorders apart in early childhood Noonan syndrome (NS) is characterized by characteristic facies, short stature, congenital heart defect, and developmental delay of variable degree. Other findings can include broad or webbed neck, unusual chest shape with superior pectus carinatum and inferior pectus excavatum, cryptorchidism, varied coagulation defects, lymphatic dysplasias, and ocular abnormalities Clinical characteristics: Noonan syndrome with multiple lentigines (NSML) is a condition in which the cardinal features consist of lentigines, hypertrophic cardiomyopathy, short stature, pectus deformity, and dysmorphic facial features, including widely spaced eyes and ptosis. Multiple lentigines present as dispersed flat, black-brown macules, mostly on the face, neck and upper part of the. Some of these other syndromes include Noonan syndrome, LEOPARD syndrome, neurofibromatosis 1 and cardio-facio-cutaneous syndrome. Ras is a critical signaling hub in the cell and is activated by receptor tyrosine kinases, G-protein-coupled receptors, cytokine receptors and extracellular matrix receptors. The downstream effectors of Ras are many. Watson syndrome is an autosomal dominant disorder characterized by pulmonic stenosis, cafe-au-lait spots, decreased intellectual ability (Watson, 1967), and short stature (Partington et al., 1985). Most affected individuals have relative macrocephaly and Lisch nodules and about one-third of those affected have neurofibroma (Allanson et al., 1991)

  1. The acronym LEOPARD syndrome, coined by Gorlin et al. (), is derived from clinical features which include lentigines, electrocardiographic conduction abnormalities, ocular hypertelorism, pulmonary stenosis, abnormal genitalia, growth retardation, and sensorineural deafness.It is also known as multiple lentigines syndrome and Moynahan syndrome and classified as a cardiocutaneous syndrome.

LEOPARD syndrome (LS) belongs to the family of neuro-cardio-facio-cutaneous syndromes, which include Neurofibromatosis-1 (NF1), Noonan syndrome, Costello Syndrome, cardio-facio-cutaneous syndrome, Noonan-like syndrome with loose anagen hair and Legius syndrome. These conditions are caused by mutations in genes encoding proteins involved in the RAS-MAPK cellular pathway

Noonan syndrome (NS) is a common, clinically and genetically heterogeneous condition characterized by distinctive facial features, short stature, chest deformity, congenital heart disease, and other comorbidities. Gene mutations identified in individuals with the NS phenotype are involved in the Ras/MAPK (mitogen-activated protein kinase) signal transduction pathway and currently explain ∼61. In addition to the disorders covered by the sub-panels, this comprehensive panel covers several other diseases associated with short stature, such as growth delay due to insulin-like growth factor I resistance or IGF1 deficiency (mutations in IGF1R and IGF1), hypothyroidism due to deficient transcription factors involved in pituitary. Carney complex (CNC; MIM #160980) is a rare multiple endocrine neoplasia syndrome characterized by distinctive pigmented lesions of the skin and mucosal surfaces, cardiac and noncardiac myxomatous tumors, and multiple endocrine tumors [ 1,2 ]. CNC is most frequently associated with mutations in the protein kinase A type I-alpha regulatory. Noonan syndrome is a genetic multisystem disorder characterised by distinctive facial features, developmental delay, learning difficulties, short stature, congenital heart disease, renal anomalies, lymphatic malformations, and bleeding difficulties.

Variants in NF1 and SPRED1 are typically loss-of-func-tion variants and include the full spectrum of nonsense, missense, splice, frameshift, insertion-deletion, and copy number changes Legius syndrome is a rare genetic disorder that was first described in 2007 [1]. It is also known as neurofibromatosis type 1-like syndrome [2]. Legius syndrome is classically characterised by multiple light-brown macules, known as café-au-lait macules [3]. Unlike neurofibromatosis type 1, there are no tumours found in Legius syndrome Hypertrophic cardiomyopathy (HCM) is a genetically heterogeneous disorder characterized by left ventricular hypertrophy (LVH) in the absence of loading conditions, such as hypertension. Although some individuals with HCM remain asymptomatic, symptoms, when present, can include shortness of breath, chest pain, palpitations, orthostasis, and syncope

Other genetic tests include biochemical tests for such gene products as enzymes and other proteins and for microscopic examination of stained or fluorescent chromosomes The Noonan Syndrome is caused by a mutation of a gene or a damaged gene that is usually inherited from one of the parents.
