Excerpt

HRAS is a member of the RAS family of GTP-binding proteins involved in cell signaling and growth promotion [1]. Costello syndrome (CS) (MIM#218040) results from activating mutations of the Ras–MAPK–ERK signaling cascade [2], often a gain of function mutation in HRAS (MIM*190020) [1]. A more recently discovered syndrome, congenital myopathy with excess of muscle spindles (CMEMS) (#218040), has also been linked to mutations of HRAS, and is considered a variant of CS. To date six cases of CMEMS have been reported [2]. We report a case of CMEMS who, to our knowledge, outlived all other reported cases of this devastating syndrome and who had autopsy results to further define the phenotype. …
