Rubinstein-Taybi syndrome due to CREBBP mutations Pathogenic:2
- -
Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with Menke-Hennekam syndrome 1 (MIM# 618332) and Rubinstein-Taybi syndrome (RTS) 1 (MIM# 180849). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0201 - Variant is predicted to cause nonsense-mediated decay (NMD) and loss of protein (premature termination codon is located at least 54 nucleotides upstream of the final exon-exon junction). (SP) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0701 - Other NMD predicted variants comparable to the one identified in this case have very strong previous evidence for pathogenicity (DECIPHER). (SP) 0803 - This variant has limited previous evidence of pathogenicity in an unrelated individual. This variant has been reported in an individual with RTS (PMID 7630403). (SP) 0905 - No published segregation evidence has been identified for this variant. (I) 1203 - This variant has been shown to be de novo in the proband (parental status confirmed) by trio analysis. (SP) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign -
