Variant summary
Our verdict is Pathogenic. Variant got 16 ACMG points: 16P and 0B. PM2PM5PP3_StrongPP5_Very_Strong
The NM_000372.5(TYR):c.613C>A(p.Pro205Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000898 in 1,614,020 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P205L) has been classified as Pathogenic.

This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 205 of the TYR protein (p.Pro205Thr). This variant is present in population databases (rs61754362, gnomAD 0.006%). This missense change has been observed in individual(s) with clinical features of oculocutaneous albinism (PMID: 13680365; internal data). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 99572). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt TYR protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. -

The TYR c.613C>A variant is predicted to result in the amino acid substitution p.Pro205Thr. This variant has been reported in multiple individuals with oculocutaneous albinism (Camand et al. 2001. PubMed ID: 11295837; King et al. 2003. PubMed ID: 13680365; Hutton and Spritz. 2008. PubMed ID: 18463683). This variant is reported in 0.0054% of alleles in individuals of European (Non-Finnish) descent in gnomAD. Given the evidence, we interpret this variant as pathogenic. -
