RCV002470658 | SCV002769508 | uncertain significance | Usher syndrome type 2A | 2021-05-06 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3A. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with Usher syndrome, type 2A (MIM#276901) and retinitis pigmentosa 39 (MIM#613809). (I) 0106 - This gene is associated with autosomal recessive disease. (I) 0200 - Variant is predicted to result in a missense amino acid change from histidine to proline. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (v2) (1 heterozygote, 0 homozygotes). (I) 0502 - Missense variant with conflicting in silico predictions and uninformative conservation. (I) 0600 - Variant is located in the annotated laminin N-terminal domain (PDB). (I) 0709 - Another missense variant comparable to the one identified in this case has previous evidence for being benign. This alternative missense variant (p.His490Asn) has been reported as likely benign (deafnessvariationdatabase). (SB) 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) 1102 - Strong phenotype match for this patient. (SP) 1201 - Heterozygous variant detected in trans with a second pathogenic heterozygous variant in a recessive disease. (SP) 1205 - This variant has been shown to be maternally inherited. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign |
