Invitae | RCV001379011 | SCV001576725 | likely pathogenic | Familial aplasia of the vermis | 2020-10-09 | criteria provided, single submitter | clinical testing | 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. 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 INPP5E protein function. This variant has been observed in individual(s) with clinical features of retinitis pigmentosa (Invitae). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. This variant is not present in population databases (ExAC no frequency). This sequence change replaces aspartic acid with asparagine at codon 438 of the INPP5E protein (p.Asp438Asn). The aspartic acid residue is highly conserved and there is a small physicochemical difference between aspartic acid and asparagine. |
