Genes affected

ADNP (HGNC:15766): (activity dependent neuroprotector homeobox) Vasoactive intestinal peptide is a neuroprotective factor that has a stimulatory effect on the growth of some tumor cells and an inhibitory effect on others. This gene encodes a protein that is upregulated by vasoactive intestinal peptide and may be involved in its stimulatory effect on certain tumor cells. The encoded protein contains one homeobox and nine zinc finger domains, suggesting that it functions as a transcription factor. This gene is also upregulated in normal proliferative tissues. Finally, the encoded protein may increase the viability of certain cell types through modulation of p53 activity. Alternatively spliced transcript variants encoding the same protein have been described. [provided by RefSeq, Jul 2008]

This sequence change creates a premature translational stop signal (p.Ser1071Argfs*9) in the ADNP gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 32 amino acid(s) of the ADNP protein. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ADNP-related conditions. ClinVar contains an entry for this variant (Variation ID: 694537). This variant disrupts a region of the ADNP protein in which other variant(s) (p.Met1088Serfs*5) have been determined to be pathogenic (PMID: 28135719). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
