Tyrosine-protein phosphatase non-receptor type 11 (PTPN11)

The protein contains 597 amino acids for an estimated molecular weight of 68436 Da.

 

Acts downstream of various receptor and cytoplasmic protein tyrosine kinases to participate in the signal transduction from the cell surface to the nucleus (PubMed:10655584, PubMed:18559669, PubMed:18829466, PubMed:26742426, PubMed:28074573). Positively regulates MAPK signal transduction pathway (PubMed:28074573). Dephosphorylates GAB1, ARHGAP35 and EGFR (PubMed:28074573). Dephosphorylates ROCK2 at 'Tyr-722' resulting in stimulation of its RhoA binding activity (PubMed:18559669). Dephosphorylates CDC73 (PubMed:26742426). Dephosphorylates SOX9 on tyrosine residues, leading to inactivate SOX9 and promote ossification (By similarity). (updated: June 17, 2020)

The reference OMIM entry for this protein is 151100

Leopard syndrome 1; lprd1
Lentiginosis, cardiomyopathic
Multiple lentigines syndrome

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.

DESCRIPTION

LEOPARD is an acronym for the manifestations of this syndrome as listed by Gorlin et al. (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. See also LEOPARD syndrome-2 (611554), caused by mutation in the RAF1 gene (164760), and LEOPARD syndrome-3 (613707), caused by mutation in the BRAF gene (164757).

CLINICAL FEATURES

Walther et al. (1966) found asymptomatic cardiac changes associated with generalized lentigo in a mother and her son and daughter. The electrocardiogram in the son suggested myocardial infarction. The mother was shown by cardiac catheterization to have mild pulmonary stenosis. Similar generalized lentigines were described by Moynahan (1962) in 3 unrelated patients (2 females, 1 male). Growth was stunted. In 1 girl, one ovary was absent and the other hypoplastic. The boy had hypospadias and undescended testes. Endocardial and myocardial fibroelastosis may have been present. Intelligence was normal but behavior childish. Matthews (1968) reported mother and 2 half-sib children with generalized lentigines, electrocardiographic changes and murmurs. A history of male-to-male transmission was recorded. Lentigines were also present in the cardiac syndrome reported by Forney et al. (see mitral regurgitation, conductive deafness, etc.; 157800). Polani and Moynahan (1972) gave a full report of 8 patients and their families. They were impressed with the occurrence of left-sided obstructive cardiomyopathy and none of their patients was deaf. They proposed the designation 'progressive cardiomyopathic lentiginosis' for this disorder. St. John Sutton et al. (1981) reported 11 patients, 10 of them male, with classic hypertrophic obstructive cardiomyopathy and lentiginosis. All were sporadic. Mental retardation, deafness, and gonadal and somatic infantilism were uncommon in this series. The 21-year-old patient of Senn et al. (1984) had severe hypertrophic obstructive cardiomyopathy for which surgery was performed on the left ventricle to relieve severe obstruction. Both parents were unaffected; both were 40 years old at the birth of the patient. Peter and Kemp (1990) described a 19-year-old woman who died as a result of respiratory insufficiency secondary to thoracic deformities which, together with a congenital heart defect, led to pulmonary hypertension. The syndrome of cafe-au-lait spots and pulmonic stenosis, described by Watson (1967), is distinct (193520). Coppin and Temple (1997) provided a review of the condition and added 5 cases, including relatives of one of the cases described by Polani and Moynahan (1972). Coppin and Temple (1997) pointed out the difficulty of differentiating LEOPARD syndrome from Noonan syndrome (163950) given previous reports of lentiginosis without lentigines. Shamsadini et al. (1999) described an 18-year-old Iranian girl with LEOPARD syndrome. Clinical manifestations included lentigines, ocular hypertelorism, mental and growth retardation, deaf mutism, and several patches of hair loss on her scalp. There was no family history of lentiginosis or any other inherited condition. Schra ... More on the omim web site
