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]

Familial hemophagocytic lymphohistiocytosis 3 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Nov 08, 2017 | For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in UNC13D are known to be pathogenic (PMID: 14622600). This variant has not been reported in the literature in individuals with UNC13D-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Leu491*) in the UNC13D gene. It is expected to result in an absent or disrupted protein product. - |
