RCV002471444 | SCV002768098 | likely pathogenic | Noonan syndrome 1 | 2021-05-06 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Likely pathogenic. Following criteria are met: 0103 - Both loss- and gain-of-function are known mechanisms of disease for this gene. Metachondromatosis (MIM#156250) and Noonan syndrome with multiple lentigines have been associated with loss of function variants, whereas Noonan syndrome 1 (MIM#163950) is caused by gain of function variants (PMIDs: 11992261, 24935154, 21533187). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0115 - Variants in this gene are known to have variable expressivity (GeneReviews). (I) 0200 - Variant is predicted to result in a missense amino acid change from arginine to glutamine. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (v2, v3) (1 heterozygote, 0 homozygotes). (I) 0501 - Missense variant consistently predicted to be damaging by multiple in silico tools or highly conserved with a major amino acid change. (SP) 0602 - Variant is located in a hotspot region or cluster of pathogenic variants (Decipher). (SP) 0701 - Other missense variants comparable to the one identified in this case have very strong previous evidence for pathogenicity. These variants, (p.Arg498Trp, p.Arg498Leu), have been reported many times as pathogenic, in individuals with either Noonan syndrome or LEOPARD syndrome (ClinVar, LOVD). (SP) 0807 - This variant has no previous evidence of pathogenicity. (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1208 - Inheritance information for this variant is not currently available in this individual. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign |
