Genes affected

ZNF778 (HGNC:26479): (zinc finger protein 778) The protein encoded by this gene is a member of the krueppel C2H2-type zinc-finger protein family, and it contains one KRAB domain and eighteen C2H2-type zinc fingers. This gene is a candidate gene for autism and variable cognitive impairment in the 16q24.3 microdeletion syndrome. Alternatively spliced transcript variants have been found for this gene.

The c.409A>G (p.R137G) alteration is located in exon 7 (coding exon 6) of the ZNF778 gene. This alteration results from a A to G substitution at nucleotide position 409, causing the arginine (R) at amino acid position 137 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
