Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine	RCV000013447	SCV000062132	pathogenic	Costello syndrome	2012-11-20	criteria provided, single submitter	clinical testing	The Gly12Cys variant in HRAS has been reported in the literature in six individu als with severe neonatal Costello syndrome (Kerr 2006, Lo 2008, Lin 2009, Niihor i 2011, Lorenz 2012). This variant has been reported to have occurred de novo in one proband (Lorenz 2012). Several other DNA variants affecting codon 12 of HRA S are commonly observed in patients with Costello syndrome (Niihori 2011). There fore, this variant is highly likely to be pathogenic.

Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 250294 control chromosomes (gnomAD). c.34G>T has been reported in the literature in multiple individuals affected with Costello Syndrome (e.g. Niihori_2011, McCormick_2013, Choi_2019). These data indicate that the variant is very likely to be associated with disease. In functional studies, Niihori et al (Niihori_2011) report that there was an increase in guanosine triphosphate (GTP)-bound HRAS and activation of RAS signaling pathway (as measured by the activation of ELK1 and c-Jun) in cells transfected with the variant of interest. In addition, HGMD database reports several other missense variants affecting the same codon and nearby codons (e.g. p.G12R, p.G12S, p.G12V, p.G12A, p.G13D, p.G13C) suggesting this area might be a mutational hotspot. Four ClinVar submitters (evaluation after 2014) cite the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.
