Invitae RCV000696329 SCV000824885 uncertain significance RASopathy 2018-01-29 criteria provided, single submitter curation This sequence change replaces glutamine with lysine at codon 61 of the NRAS protein (p.Gln61Lys). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and lysine. This variant is not present in population databases (ExAC no frequency). While this variant has been published in the literature (PMID: 23392294), it has not been reported in the germline of an individual with NRAS-related disease. ClinVar contains an entry for this variant (Variation ID: 73058). This variant has been reported as a recurrent variant in melanoma tumors (PMID: 23392294), colorectal tumors (PMID: 27050078, 23400451), thyroid tumors (PMID: 28780248), squamous cell lung tumors (PMID: 25348872), neuroblastoma tumors (PMID: 26821351), and gynecological tumors (PMID: 24671188). Experimental studies have shown that this missense change p.Gln61Lys, results in cytoskeletal changes in melanocyte cell lines, reduces apoptosis, and results in hyperpigmented skin in transgenic mice who develop cutaneous metastasizing melanoma (PMID: 22718121, 18668139, 15899789). However, in a thyroid epithelial cell line, this variant alone resulted in zero tumor instances (PMID: 10821536). In zebrafish, expression of human NRAS p.Q61K in melanocytes results in the growth of pigmented lesions that rarely progress to melanoma. (PMID: 24148783). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.

Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV000114746 SCV002769261 pathogenic Large congenital melanocytic nevus 2020-05-21 criteria provided, single submitter clinical testing A heterozygous missense variant was identified, NM_002524.3(NRAS):c.181C>A in exon 3 of the NRAS gene. This substitution is predicted to create a minor amino acid change from a glutamine to a lysine at position 61 of the protein; NP_002515.1(NRAS):p.(Gln61Lys). The glutamine at this position has very high conservation (100 vertebrates, UCSC), and is located within the switch II region (Cirstea, I. C. et al. (2010)). In silico software predicts this variant to be damaging (PolyPhen2, PROVEAN, MutationAssessor, FATHMM). The variant is not present in the gnomAD population database. This variant has been previously reported as pathogenic in multiple patients with congenital melanocytic naevi (ClinVar, Kinsler, V. A. et al. (2013)). In addition, functional studies show that this variant causes melanocyte survival and growth in the epidermis (Li, A. et al. (2012)). Different variants in the same codon resulting in changes to histidine, leucine, arginine, proline and glutamic acid, have also been reported as pathogenic (ClinVar). Based on information available at the time of curation, this variant has been classified as PATHOGENIC.
