Studies on the pathogenesis of Costello syndrome.
Costello syndrome is characterised by high birth weight, early psychomotor and growth retardation, cardiomyopathy, relative macrocephaly, coarse face, and laxity of the small joints. Skin abnormalities include nasal and perianal papillomata, acanthosis nigricans, cutis laxa, and curly and sparse scalp hair. 2 Increased paternal age and sporadic occurrence have suggested autosomal dominant de no...
متن کاملCostello syndrome.
Costello syndrome is a rare, distinctive, multiple congenital anomaly syndrome, characterized by soft, loose skin with deep palmar and plantar creases, loose joints, distinctive coarse facial features and skeletal and cardiac abnormalities. The affected patients have a predisposition to develop malignancy, developmental delays and mental retardation. Recently, a 7-year-old male child born to no...
متن کاملThe Splicing Efficiency of Activating HRAS Mutations Can Determine Costello Syndrome Phenotype and Frequency in Cancer
Costello syndrome (CS) may be caused by activating mutations in codon 12/13 of the HRAS proto-oncogene. HRAS p.Gly12Val mutations have the highest transforming activity, are very frequent in cancers, but very rare in CS, where they are reported to cause a severe, early lethal, phenotype. We identified an unusual, new germline p.Gly12Val mutation, c.35_36GC>TG, in a 12-year-old boy with attenuat...
متن کاملAnaesthetic Management in Costello Syndrome.
Costello syndrome is a rare genetic disorder characterised by growth and mental retardation, macrocephaly, short neck and macroglossia. Cardiac involvement can also occur in Costello syndrome and is presented in the form of hypertrophic cardiomyopathy, tachyarrythmias and valvular dysfunction. Nervous system involvement including ventriculomegaly, hydrocephaly and Chiari type 1 malformation are...
متن کاملCraniofacial and dental development in Costello syndrome.
Costello syndrome (CS) is a RASopathy characterized by a wide range of cardiac, musculoskeletal, dermatological, and developmental abnormalities. The RASopathies are defined as a group of syndromes caused by activated Ras/mitogen-activated protein kinase (MAPK) signaling. Specifically, CS is caused by activating mutations in HRAS. Although receptor tyrosine kinase (RTK) signaling, which is upst...
