Kids Neuroscience Centre, Sydney Children's Hospitals Network RCV001726503 SCV001571491 likely pathogenic Intellectual disability-facial dysmorphism syndrome due to SETD5 haploinsufficiency criteria provided, single submitter clinical testing The c.960-5C>G variant induces exon 10 skipping (p.(Pro321Cysfs*4)) causing a frameshift, encoding 4 missense amino acids and a premature termination codon. These transcripts are predicted to be targeted for nonsense-mediated decay. Any mis-spliced SETD5 transcripts with exon 10 skipping that escape nonsense-mediated decay encode SETD5 proteins missing 1121 amino acids (p.(Pro321_Ser1442del)) from the C-terminus.
Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV001726503 SCV002766666 pathogenic Intellectual disability-facial dysmorphism syndrome due to SETD5 haploinsufficiency 2020-10-19 criteria provided, single submitter clinical testing Based on the classification scheme VCGS_Germline_v1.1.1, this variant is classified as Pathogenic. Following criteria are met: 0102 - Loss-of-function is a known mechanism of disease for this gene. (N) 0107 - This gene is known to be associated with autosomal dominant disease. (N) 0201 - Variant is predicted to cause nonsense-mediated decay (NMD) and loss of protein (intron 19 of 22) (P) 0210 - Splice site variant (canonical or non-canonical) proven to affect splicing/expression of the transcript with a known effect on protein structure. This variant has been proven to result in aberrant splicing resulting in out-of-frame exon 10 skipping, p.(Pro321Cysfs*4) (Splicing Diagnostics, Kid’s Neuroscience Centre) (N) 0251 - Variant is heterozygous. (N) 0301 - Variant is absent from gnomAD. (P) 0508 – In silico predictions for abnormal splicing are conflicting. (N) 0701 - Comparable variants have very strong previous evidence for pathogenicity. Many other NMD predicted variants have been reported as pathogenic in patients with SETD5-related intellectual disability (ClinVar, PMID: 28905509) (P) 0807 - Variant has not previously been reported in a clinical context. (N) 0905 - No segregation evidence has been identified for this variant. (N) 1007 - No published functional evidence has been identified for this variant. (N) 1204 - Variant shown to be de novo in proband (parental status not tested but assumed). (P) Legend: (P) - Pathogenic, (N) - Neutral, (B) - Benign
