Genes affected

TAT (HGNC:11573): (tyrosine aminotransferase) This nuclear gene encodes a mitochondrial protein tyrosine aminotransferase which is present in the liver and catalyzes the conversion of L-tyrosine into p-hydroxyphenylpyruvate. Mutations in this gene cause tyrosinemia (type II, Richner-Hanhart syndrome), a disorder accompanied by major skin and corneal lesions, with possible cognitive disability. A regulator gene for tyrosine aminotransferase is X-linked. [provided by RefSeq, Jul 2008]

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant is present in population databases (rs758306831, gnomAD 0.007%). This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 119 of the TAT protein (p.Arg119Trp). This missense change has been observed in individuals with tyrosinemia type II (PMID: 9544843, 25784227, 28255985; Invitae). ClinVar contains an entry for this variant (Variation ID: 550997). 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 TAT protein function. For these reasons, this variant has been classified as Pathogenic. -
