Genes affected
UNC13D (HGNC:23147): (unc-13 homolog D) This gene encodes a protein that is a member of the UNC13 family, containing similar domain structure as other family members but lacking an N-terminal phorbol ester-binding C1 domain present in other Munc13 proteins. The protein appears to play a role in vesicle maturation during exocytosis and is involved in regulation of cytolytic granules secretion. Mutations in this gene are associated with familial hemophagocytic lymphohistiocytosis type 3, a genetically heterogeneous, rare autosomal recessive disorder. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -10 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.66).
BP6
Variant 17-75828797-G-T is Benign according to our data. Variant chr17-75828797-G-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 325243.
BP7
Synonymous conserved (PhyloP=-0.468 with no splicing effect.
BS1
Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.0000237 (33/1394594) while in subpopulation MID AF = 0.00151 (7/4632). AF 95% confidence interval is 0.000709. There are 0 homozygotes in GnomAdExome4. There are 16 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
