Invitae | RCV001047233 | SCV001211173 | pathogenic | X-linked severe congenital neutropenia; Thrombocytopenia 1; Wiskott-Aldrich syndrome | 2022-04-13 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 58 of the WAS protein (p.Pro58Thr). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with clinical features of Wiskott-Aldrich syndrome (PMID: 20173115; Invitae). ClinVar contains an entry for this variant (Variation ID: 844399). 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 WAS protein function. This variant disrupts the p.Pro58 amino acid residue in WAS. Other variant(s) that disrupt this residue have been observed in individuals with WAS-related conditions (PMID: 11877312, 15284122), which suggests that this may be a clinically significant amino acid residue. For these reasons, this variant has been classified as Pathogenic. |
