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

Classification made for transcript

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

PVS1
Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.125 CDS is truncated, and there are 1 pathogenic variants in the truncated region.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 10-102067512-C-T is Pathogenic according to our data. Variant chr10-102067512-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 431051.Status of the report is criteria_provided_single_submitter, 1 stars.

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 31, 2023This sequence change creates a premature translational stop signal (p.Gln680*) in the HPS6 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 96 amino acid(s) of the HPS6 protein. This variant is present in population databases (no rsID available, gnomAD 0.02%). This premature translational stop signal has been observed in individual(s) with clinical features of HPS6-related conditions and/or Hermansky-Pudlak syndrome (PMID: 27225848, 29054114, 31141302). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 431051). For these reasons, this variant has been classified as Pathogenic. -
