Bleeding and platelet disorders v1.9 | BLOC1S5 |
Zornitza Stark gene: BLOC1S5 was added gene: BLOC1S5 was added to Bleeding and platelet disorders. Sources: Literature Mode of inheritance for gene: BLOC1S5 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: BLOC1S5 were set to 32565547 Phenotypes for gene: BLOC1S5 were set to Hermansky–Pudlak syndrome Review for gene: BLOC1S5 was set to GREEN gene: BLOC1S5 was marked as current diagnostic Added comment: 2 unrelated patients with mild oculocutaneous albinism, moderate bleeding diathesis, platelet aggregation deficit, and a dramatically decreased number of platelet dense granules, all signs compatible with HPS. Identified distinct homozygous variants in the BLOC1S5 gene (patient 1: deletion of exons 3 and 4, patient 2: 1-bp deletion in exon 4). Parental segregation confirmatory in patient 1, quantitative PCR analysis confirmatory in patient 2). Functional tests performed on platelets of one patient displayed an absence of the obligate multisubunit complex BLOC-1, showing that the variant disrupts BLOC1S5 function and impairs BLOC-1 assembly. Expression of the patient-derived BLOC1S5 deletion in nonpigmented murine Bloc1s5-/- melan-mu melanocytes failed to rescue pigmentation, the assembly of a functional BLOC-1 complex, and melanosome cargo trafficking, unlike the wild-type allele. Pathogenic variants in the genes encoding three other BLOC-1 subunits (DTNBP1, BLOC1S3, and BLOC1S6) underlie HPS types 7, 8, and 9 respectively. Sources: Literature |
