Description : Costello syndrome is a rare multiple congenital anomaly syndrome associated in all
cases with a characteristic coarse facies, short stature, distinctive hand posture
and appearance, severe feeding difficulty, and failure to thrive. Other features include
cardiac anomalies and developmental disability. Facial warts, particularly nasolabial,
are often present in childhood (Kerr et al., 2006). In patients with a clinical diagnosis
of Costello syndrome, Zenker et al. (2007) identified mutations in the KRAS gene,
but noted that these patients may later develop features of CFC syndrome. In either
case, the findings underscore the central role of Ras in the pathogenesis of these
phenotypically related disorders (Zenker et al., 2007). However, Kerr et al. (2008)
commented that the diagnosis of Costello syndrome should only be used to refer to
patients with mutations in the HRAS gene.;
