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]

Ambry Genetics

Nov 17, 2023

The c.616A>T (p.I206F) alteration is located in exon 5 (coding exon 5) of the ZBP1 gene. This alteration results from a A to T substitution at nucleotide position 616, causing the isoleucine (I) at amino acid position 206 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
