Genes affected

HPS6 (HGNC:18817): (HPS6 biogenesis of lysosomal organelles complex 2 subunit 3) This intronless 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 5 protein. Mutations in this gene are associated with Hermansky-Pudlak syndrome type 6. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PVS1: Start lost variant, next in-frame start position is after 6 pathogenic variants. Next in-frame start position is after 227 codons. Genomic position: 102066153. Lost 0.292 part of the original CDS.
• PM2: Very rare variant in population databases, with high coverage
