| Invitae | RCV000790400 | SCV002272672 | likely pathogenic | Severe combined immunodeficiency, autosomal recessive, T cell-negative, B cell-negative, NK cell-negative, due to adenosine deaminase deficiency | 2021-12-17 | criteria provided, single submitter | clinical testing | ClinVar contains an entry for this variant (Variation ID: 635324). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant disrupts the p.His15Asp amino acid residue in ADA. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 7599635, 9758612, 26376800, 27129325). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt ADA protein function. This variant has not been reported in the literature in individuals affected with ADA-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces histidine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 15 of the ADA protein (p.His15Leu). |
