Genes affected
DTNBP1 (HGNC:17328): (dystrobrevin binding protein 1) This gene encodes a protein that may play a role in organelle biogenesis associated with melanosomes, platelet dense granules, and lysosomes. A similar protein in mouse is a component of a protein complex termed biogenesis of lysosome-related organelles complex 1 (BLOC-1), and binds to alpha- and beta-dystrobrevins, which are components of the dystrophin-associated protein complex (DPC). Mutations in this gene are associated with Hermansky-Pudlak syndrome type 7. This gene may also be associated with schizophrenia. Multiple transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.45).
BP6
Variant 6-15524635-G-A is Benign according to our data. Variant chr6-15524635-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 210858.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Likely_benign=1, Benign=1}. Variant chr6-15524635-G-A is described in Lovd as [Benign].
BP7
Synonymous conserved (PhyloP=-0.025 with no splicing effect.
BS1
Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00326 (496/152272) while in subpopulation SAS AF = 0.00539 (26/4824). AF 95% confidence interval is 0.00378. There are 1 homozygotes in GnomAd4. There are 227 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position FAILED quality control check.
BS2
High Homozygotes in GnomAdExome4 at 23 AR gene
