Filtering for rare protein-changing variants revealed an independent homozygous variant that could be the cause in each case: a likely pathogenic missense variant in TYR (NP_851344.1:p.Pro428Leu) in case 1 with oculocutaneous albinism type 1, a likely pathogenic missense variant in GRID1 (XP_024842694.1:p.Pro489His) in case 2 with short stature-auditory depigmentation syndrome, and a frameshift variant of uncertain significance in RAD54B (NP_001179884.1:p.Ala722_Gly724delinsAsnLeuIlePheCys*) in case 3 with a multisystem depigmentation syndrome. The gene discussed is GRID1; the disease is oculocutaneous albinism type 1.
