Genes affected

ZNF816-ZNF321P (HGNC:38879): (ZNF816-ZNF321P readthrough) This locus represents naturally occurring read-through transcription between the zinc finger protein 816 (ZNF816) gene and the zinc finger protein 321 (ZNF321) pseudogene on chromosome 19. The read-through transcript encodes a KRAB domain-containing protein that shares sequence identity with the upstream gene product, but it contains a distinct C-terminus encoded by exon structure from the downstream pseudogene.

The c.584G>T (p.R195I) alteration is located in exon 4 (coding exon 3) of the ZNF816-ZNF321P gene. This alteration results from a G to T substitution at nucleotide position 584, causing the arginine (R) at amino acid position 195 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
