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 -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.016261786).

BP6

Variant 17-75830364-T-C is Benign according to our data. Variant chr17-75830364-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 533103.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00152 (232/152318) while in subpopulation AFR AF = 0.00481 (200/41568). AF 95% confidence interval is 0.00426. There are 0 homozygotes in GnomAd4. There are 106 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
