Foundation for Research in Genetics and Endocrinology,Institute of Human Genetics RCV000850231 SCV000965690 likely pathogenic Tyrosinase-negative oculocutaneous albinism; Oculocutaneous albinism type 1B 2019-06-21 criteria provided, single submitter clinical testing A heterozygous variant c.121G>A (p.Gly41Arg) in exon-1 has been observed in the TYR gene. The proband, born of a non-consanguineous marriage, was suspected to be affected with albinism. The patient in our clinical analysis was observed with the said variant in an autosomal recessive mode of inheritance. The variant has not been reported in the 1000 genomes database and has a minor allele frequency of 0.0008% and 0.007% in the ExAC databases. The in silico predictions of the variant are probably damaging by PolyPhen-2 (HumDiv), SIFT, LRT and MutationTaster2. In summary, the said variant meets our criteria to be classified as likely pathogenic based on the mode of inheritance, in silico prediction and allele frequency in population databases.
