Genes affected
ZBP1 (HGNC:16176): (Z-DNA binding protein 1) This gene encodes a Z-DNA binding protein. The encoded protein plays a role in the innate immune response by binding to foreign DNA and inducing type-I interferon production. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 22, 2023The c.1020G>A (p.M340I) alteration is located in exon 7 (coding exon 7) of the ZBP1 gene. This alteration results from a G to A substitution at nucleotide position 1020, causing the methionine (M) at amino acid position 340 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
