Invitae RCV003064290 SCV003443026 pathogenic Tyrosinemia type I 2022-06-04 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects FAH function (PMID: 31300554). 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 FAH protein function. This missense change has been observed in individual(s) with tyrosinemia type 1 (PMID: 8723690; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 249 of the FAH protein (p.Pro249Thr).
