Description : Hermansky-Pudlak syndrome (HPS) is a rare autosomal recessive disorder in which oculocutaneous albinism, bleeding, and lysosomal ceroid storage result from defects of multiple cytoplasmic organelles: melanosomes, platelet-dense granules, and lysosomes (Oh et al., 1998). - Genetic Heterogeneity of Hermansky-Pudlak Syndrome Hermansky-Pudlak syndrome can also be caused by homozygous or compound heterozygous mutations in several other genes. HPS2 (608233), which includes immunodeficiency in its phenotype, is caused by mutation in the AP3B1 gene (603401) on chromosome 5q14.1. HPS3 (614072) is caused by mutation in a gene on chromosome 3q24 (606118); HPS4 (614073) is caused by mutation in a gene on chromosome 22q11.2-q12 (606682); HPS5 (614074) is caused by mutation in a gene on chromosome 11p14 (607521); HPS6 (614075) is caused by mutation in a gene on chromosome 10q24 (607522); HPS7 (614076) is caused by mutation in the DTNBP1 gene (607145) on chromosome 6p22; HPS8 (614077) is caused by mutation in the BLOC1S3 gene (609762) on chromosome 19q13.32; and HPS9 (614171) is caused by mutation in the PLDN gene (604310) on chromosome 15q21.1.;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the HPS1 biogenesis of lysosomal organelles complex 3 subunit 1 gene (HPS1, 203300);

Laboratory abnormalities : Hair bulb tyrosinase present;

Prefixed ID : #203300;
