Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV004595335 SCV005086517 uncertain significance Shukla-Vernon syndrome 2024-10-09 criteria provided, single submitter clinical testing Based on the classification scheme VCGS_Germline_v1.3.5, this variant is classified as VUS-3A. Following criteria are met: 0105 - The mechanism of disease for this gene is not clearly established. (I) 0109 - This gene is associated with X-linked recessive disease. Carrier females may have mild manifestations (PMID: 33810051). (I) 0115 - Variants in this gene are known to have variable expressivity. The degree of intellectual disability varies from mild to severe among patients (PMID: 33810051). (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 (v2, v3 and v4). (SP) 0309 - An alternative NMD-predicted variant has been observed in gnomAD (v2) (3 heterozygotes, 0 homozygotes, 1 hemizygote). (I) 0704 - Other NMD-predicted variants comparable to the one identified in this case have limited previous evidence for pathogenicity. Three NMD-predicted variants have been classified as likely pathogenic or pathogenic and have been associated with Shukla-Vernon syndrome (ClinVar, PMID: 36553572). However, it should also be noted that there are multiple NMD-predicted variants that have been classified as a VUS. (SP) 0807 - This variant has no previous evidence of pathogenicity. (I) 0906 - Segregation evidence for this variant is inconclusive. This variant was shown to be heterozygous in this individual's mildly affected sister but also in her mother who is possibly unaffected. The variant was also not present in another mildly affected sister of this individual (VCGS internal data). (I) 1007 - No published functional evidence has been identified for this variant. (I) 1205 - This variant has been shown to be maternally inherited (by duo analysis). (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
