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 made for transcript

Verdict is Benign. Variant got -14 ACMG points.

BP4

This position, referring to a specific DNA site, is a probable branch point but is likely benign (scored 2 / 10, using the threshold of <=3). The score ranges from 0 to 10, with values ≤3 considered benign and >5 classified as pathogenic. Computational evidence support a benign effect (BayesDel_noAF=-0.81).

BP6

Variant 17-75840607-G-A is Benign according to our data. Variant chr17-75840607-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 263243.Status of the report is criteria_provided_single_submitter, 1 stars.

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00338 (514/152236) while in subpopulation AFR AF= 0.0117 (486/41536). AF 95% confidence interval is 0.0108. There are 1 homozygotes in gnomad4. There are 254 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

BS2
