Growth delay due to IGF-I resistance is characterised by variable intrauterine and postnatal growth retardation and elevated serum IGF-I levels. Addition features include variable degrees of intellectual deficit, microcephaly and dysmorphism (broad nasal bridge and tip, smooth philtrum, thin upper and everted lower lips, short fingers, clinodactyly, wide-set nipples and pectus excavatum).

Noonan syndrome-like disorder with juvenile myelomonocytic leukemia is a rare, genetic, polymalformative syndrome with increased risk of developing cancer characterized by a Noonan-like phenotype, including typical dysmorphic facial features (i.e. high forehead, hypertelorism, downslanting palpebral fissures, ptosis, low-set ears, prominent philtrum and short neck with or without pterygium colli), thoracic abnormalities, congenital heart defects and short stature, associated with a very frequent ocurrence of juvenile myelomonocytic leukemia. Developmental delay, ectodermal anomalies, joint laxity, and hypotonia may also be associated.

Seckel syndrome is a rare autosomal recessive disorder characterized by intrauterine growth retardation, dwarfism, microcephaly with mental retardation, and a characteristic 'bird-headed' facial appearance (Shanske et al., 1997). Genetic Heterogeneity of Seckel SyndromeOther forms of Seckel syndrome include SCKL2 (OMIM ), caused by mutation in the RBBP8 gene (OMIM ) on chromosome 18q11; SCKL4 (OMIM ), caused by mutation in the CENPJ gene (OMIM ) on chromosome 13q12; SCKL5 (OMIM ), caused by mutation in the CEP152 gene (OMIM ) on chromosome 15q21; SCKL6 (OMIM ), caused by mutation in the CEP63 gene (OMIM ) on chromosome 3q22; SCKL7 (OMIM ), caused by mutation in the NIN gene (OMIM ) on chromosome 14q22; SCKL8 (OMIM ), caused by mutation in the DNA2 gene (OMIM ) on chromosome 10q21; SCKL9 (OMIM ), caused by mutation in the TRAIP gene (OMIM ) on chromosome 3p21; and SCKL10 (OMIM ), caused by mutation in the NSMCE2 gene (OMIM ) on chromosome 8q24.The report of a Seckel syndrome locus on chromosome 14q, designated SCKL3, by Kilinc et al. (2003) was found to be in error; see HISTORY.

Noonan syndrome (NS) is an autosomal dominant disorder characterized by short stature, facial dysmorphism, and a wide spectrum of congenital heart defects. The distinctive facial features consist of a broad forehead, hypertelorism, downslanting palpebral fissures, a high-arched palate, and low-set, posteriorly rotated ears. Cardiac involvement is present in up to 90% of patients. Pulmonic stenosis and hypertrophic cardiomyopathy are the most common forms of cardiac disease, but a variety of other lesions are also observed. Additional relatively frequent features include multiple skeletal defects (chest and spine deformities), webbed neck, mental retardation, cryptorchidism, and bleeding diathesis (summary by Tartaglia et al., 2002).
