Costello syndrome

Costello syndrome

A rare hereditary disease (OMIM:218040) that overlaps cardiofaciocutaneous and Noonan syndromes, characterised by excess prenatal and defective postpartum growth, mental retardation, characteristic coarse facies, short stature, cardiovascular defects (e.g., pulmonary stenosis, hypertrophic cardiomyopathy, atrial tachycardia), increased risk of papillomas and rhabdomyosarcomas, and cutaneous and musculoskeletal defects.

Molecular pathology
Defects in HRAS, an oncogene on chromosome 11p15.5 whose protein product plays key roles in signal transduction, cause Costello syndrome.

This signalling cascade is also involved in many other inherited conditions such as cardiofaciocutaneous syndrome (CFCS), LEOPARD syndrome (LS), Costello syndrome (CS), and type 1 neurofibromatosis (NF1) [11] (Figure 6).
These disorders include neurofibromatosis type 1 (NF1, OMIM 162200), Legius syndrome (NFLS, OMIM 611431), Noonan syndrome (NS, OMIM 163950), Noonan syndrome with multiple lentigines (also called LEOPARD syndrome, LS, OMIM 151100), Costello syndrome (CS, OMIM 218040), cardiofaciocutaneous syndrome (CFCS, OMIM 115100), Noonan-like syndromes, hereditary gingival fibromatosis (HGF, OMIM 135300), and capillary malformation-arteriovenous malformation (CMAVM, OMIM 608354).
Costello syndrome (CS) (OMIM #218040) is a rare disorder with a distinctive prenatal presentation, postnatal feeding difficulties and failure to thrive, characteristic facial appearance (coarse features, full lips, and large mouth), abnormalities of the heart (hypertrophic cardiomyopathy, pulmonary valve stenosis, and tachyarrhythmia), skin and musculoskeletal system (soft skin, deep palmar and plantar creases, papillomata, sparse or curly hair, joint laxity, ulnar deviation of wrist and fingers, and tight Achilles tendons), and tumor predisposition such as rhabdomyosarcoma (RMS), neuroblastoma, or transitional cell carcinoma of the bladder [1].
The primary goal of the current research was to understand the role of a cell-signaling pathway called RAS/MAPK in the cascade of events leading to HCM in patients with CFCs, and by association, with Noonan syndrome, Costello syndrome, and other similar illnesses.
Costello syndrome is a rare genetic disease characterized by coarse facies, short stature, loose folds of skin on the hands and feet, severe feeding difficulties and failure to thrive, cardiac anomalies, developmental disability, and increased risk of malignancies, especially rhabdomyosarcoma, with an approximately 15% lifetime risk.

However, there have been case reports of bladder tumors in children with Costello syndrome, a rare autosomal dominant disorder associated with mutations in the Kristen rat sarcoma viral onocogene homolog (KRAS) gene that confer increased risk for other non-urologic malignancies (Franceschini et al., 1999; Gripp, Scott, Nicholson, & Figueroa, 2000; Urakami et al., 2002).
