Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV004594772 SCV005086269 uncertain significance Rauch-Steindl syndrome 2023-07-17 criteria provided, single submitter clinical testing Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3B. Following criteria are met: 0103 - Loss of function and gain of function are known mechanisms of disease in this gene and are associated with Rauch-Steindl syndrome (MIM#619695) and a neurodevelopmental disorder, NSD2-related (MONDO:0700092), respectively. A single recurring missense variant with a gain of function mechanism has been reported to cause a more severe neurodevelopmental disorder, whereas loss of function missense variants and those resulting in a premature termination codon have been reported to cause Rauch-Steindl syndrome (PMID: 36189577, PMID: 33941880). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0200 - Variant is predicted to result in a missense amino acid change from arginine to glutamine. (I) 0251 - This variant is heterozygous. (I) 0302 - Variant is present in gnomAD (v3) <0.001 for a dominant condition (1 heterozygote, 0 homozygotes). (SP) 0502 - Missense variant with conflicting in silico predictions and uninformative conservation. (I) 0604 - Variant is not located in an established domain, motif, hotspot or informative constraint region. (I) 0705 - No comparable missense variants have previous evidence for pathogenicity. (I) 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) 1207 - Parental origin of the variant is unresolved. Duo analysis has proven that this variant is NOT maternally inherited. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
