These variants have been previously reported as disease-causing [PMID 1642278, 28266639, 1903591, 27775880, 25333069, 21906913, 28667292, 24123366, 9242509, 11284711, 1429711]

Labcorp Genetics (formerly Invitae), Labcorp	RCV000085962	SCV002121290	pathogenic	not provided	2024-10-27	criteria provided, single submitter	clinical testing	This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 217 of the TYR protein (p.Arg217Trp). This variant is present in population databases (rs63159160, gnomAD 0.04%). This missense change has been observed in individual(s) with ocular albinism (PMID: 1642278, 10987646, 27734839, 28266639). 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: 3795). 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) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on TYR protein function. For these reasons, this variant has been classified as Pathogenic.

Clinical Genomics Laboratory, Washington University in St. Louis	RCV004795373	SCV005688757	pathogenic	Tyrosinase-negative oculocutaneous albinism; Oculocutaneous albinism type 1B	2024-09-22	criteria provided, single submitter	clinical testing	The TYR c.649C>T (p.Arg217Trp) variant has been reported in several individuals affected with oculocutaneous albinism in the compound heterozygous state (Mauri L et al., PMID: 27734839; Passmore LA et al., PMID: 10987646; Shahzad M et al., PMID: 28266639). This variant has been reported in the ClinVar database as a germline pathogenic or likely pathogenic variant by several submitters and a variant of uncertain significance by one submitter. This variant is only observed on 54/282,142 alleles in the general population (gnomAD v.2.1.1), indicating it is not a common variant. Computational predictors are uncertain as to the impact of this variant on TYR function. Based on available information and the ACMG/AMP guidelines for variant interpretation (Richards S et al., PMID: 25741868), this variant is classified as pathogenic.
