The c.1091_1093delAGA variant in the SMARCB1 gene is a recurrent pathogenic variant seen in individuals with Coffin-Siris syndrome (Tsurusaki et al., 2012; Santen et al., 2013; Kosho et al., 2014; Tsurusaki et al., 2014). The c.1091_1093delAGA variant causes an in-frame deletion of codon Lysine 364, denoted p.Lys364del. The c.1091_1093delAGA variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. We interpret c.1091_1093delAGA as a pathogenic variant. (less)

This variant has been observed in individual(s) with clinical features of Coffin-Siris syndrome (PMID: 22426308, 23815551, 23929686, 25533962). In at least one individual the variant was observed to be de novo. For these reasons, this variant has been classified as Pathogenic. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. ClinVar contains an entry for this variant (Variation ID: 30201). This variant is not present in population databases (gnomAD no frequency). This variant, c.1091_1093del, results in the deletion of 1 amino acid(s) of the SMARCB1 protein (p.Lys364del), but otherwise preserves the integrity of the reading frame. (less)

Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0103 - Dominant negative, loss of function and gain of function are all known mechanisms of disease in this gene. Loss of function variants are associated with cancer susceptibility (rhabdoid tumor predisposition syndrome 1 (MIM#609322), schwannomatosis-1 (MIM#162091), rhabdoid tumors somatic (MIM#609322)). An inframe deletion variant, missense variants and truncating variants escaping nonsense-mediated decay have been reported to have either a gain of function or dominant negative mechanism, and are all associated with Coffin-Siris syndrome 3 (MIM#614608) (OMIM, PMID: 31759698). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0213 - In-frame insertion/deletion in a non-repetitive region that has high conservation. (SP) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0602 - Variant is located in a hotspot region or cluster of pathogenic variants (DECIPHER, PMID: 31759698). (SP) 0801 - This variant has strong previous evidence of pathogenicity in unrelated individuals. This variant has been reported multiple times as pathogenic and de novo in individuals with Coffin-Siris syndrome (PMID: 31759698, ClinVar, DECIPHER). (SP) 1203 - This variant has been shown to be de novo in the proband (parental status confirmed, by trio analysis).

The c.1091_1093delAGA (p.K364del) alteration, located in coding exon 8 of the SMARCB1 gene, results from an in-frame deletion of 3 nucleotides at positions c.1091 toc.1093. This results in the deletion of 1 amino acid at codon 364. _x000D_ _x000D_ Based on the available evidence, the SMARCB1 c.1091_1093delAGA (p.K364del) alteration is classified as pathogenic for SMARCB1-related Coffin-Siris syndrome; however, its clinical significance for SMARCB1-related tumor predisposition syndrome is uncertain. This variant was not reported in population-based cohorts in the Genome Aggregation Database (gnomAD). This alteration has been reported in multiple individuals with a clinical diagnosis of Coffin-Siris syndrome, including several with confirmed de novo origin (Tsurusaki, 2012; Santen, 2013; Kosho, 2013; Kosho, 2014; Miyake, 2014; Sekiguchi, 2019). This amino acid position is highly conserved in available vertebrate species. In vitro and cell-based functional studies demonstrated this alteration results in reduced mSWI/SNF functional activity and is defective in generating DNA accessibility and in activating critical target genes (Valencia, 2019). This alteration is predicted to be deleterious by in silico analysis (Choi, 2012). Based on the available evidence, this alteration is classified as pathogenic. (less)

In 3 patients (patients 4, 21, and 22) with Coffin-Siris syndrome (CSS3; 614608), Tsurusaki et al. (2012) identified a heterozygous 3-bp in-frame deletion in the SMARCB1 gene (1091_1093delAGA) that resulted in deletion of lysine-364 (lys364del). The mutation was de novo in 2 cases, and parental samples were unavailable in the third. This mutation was not seen in any of 502 Japanese control chromosomes. (less)
