Genes affected

HPS5 (HGNC:17022): (HPS5 biogenesis of lysosomal organelles complex 2 subunit 2) This gene encodes a protein that may play a role in organelle biogenesis associated with melanosomes, platelet dense granules, and lysosomes. This protein interacts with Hermansky-Pudlak syndrome 6 protein and may interact with the cytoplasmic domain of integrin, alpha-3. Mutations in this gene are associated with Hermansky-Pudlak syndrome type 5. Multiple transcript variants encoding two distinct isoforms have been identified for this gene.

Pro846Leu in exon 17 of HPS5: This variant is not expected to have clinical sign ificance because it has been identified in 5.5% (6/110) of Puerto Rican chromoso mes from a broad population by the 1000 Genomes Project (http://www.ncbi.nlm.nih .gov/projects/SNP; dbSNP rs144875223). -

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
