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.

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BP6: Variant 11-18279812-G-A is Benign according to our data. Variant chr11-18279812-G-A is described in ClinVar as Likely_benign. ClinVar VariationId is 303864.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000979 (149/152272) while in subpopulation SAS AF = 0.00477 (23/4822). AF 95% confidence interval is 0.00326. There are 1 homozygotes in GnomAd4. There are 72 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High Homozygotes in GnomAdExome4 at 19 AR gene
