Victorian Clinical Genetics Services, Murdoch Childrens Research Institute	RCV002472268	SCV002769387	uncertain significance	Macrothrombocytopenia and granulocyte inclusions with or without nephritis or sensorineural hearing loss	2020-10-19	criteria provided, single submitter	clinical testing	Based on the classification scheme VCGS_Germline_v1.1.1, this variant is classified as 3C-VUS. Following criteria are met: 0102 - Loss-of-function is a known mechanism of disease for this gene. (N) 0104 - Dominant Negative is a mechanism of disease for this gene. (N) 0107 - This gene is known to be associated with autosomal dominant disease. (N) 0200 - Variant is predicted to result in a missense amino acid change from alanine to valine. (N) 0251 - Variant is heterozygous. (N) 0301 - Variant is absent from gnomAD. (P) 0503 - Missense variant consistently predicted to be tolerated or not conserved in mammals with a minor amino acid change. (B) 0504 - Same amino acid change has been observed in mammals. (B) 0600 - Variant is located in an annotated domain or motif. (Myosin tail, PDB, NCBI, DECIPHER) (N) 0705 - No comparable variants have previous evidence for pathogenicity. (N) 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) 1208 – Inheritance information for this variant is not currently available. (N) Legend: (P) - Pathogenic, (N) - Neutral, (B) - Benign
PreventionGenetics, part of Exact Sciences	RCV004733509	SCV005342164	uncertain significance	MYH9-related disorder	2024-03-28	no assertion criteria provided	clinical testing	The MYH9 c.5657C>T variant is predicted to result in the amino acid substitution p.Ala1886Val. To our knowledge, this variant has not been reported in the literature or in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
