Genes affected
PRUNE1 (HGNC:13420): (prune exopolyphosphatase 1) This gene encodes a member of the DHH protein superfamily of phosphoesterases. This protein has been found to function as both a nucleotide phosphodiesterase and an exopolyphosphatase. This protein is believed to stimulate cancer progression and metastases through the induction of cell motility. A pseuodgene has been identified on chromosome 13. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2014]

The missense variant c.316G>A (p.Asp106Asn) in PRUNE1 gene has been reported to be homozygous in several individuals with syndromic intellectual disability (Karaca E et.al.,2015). Experimental studies show that missense change affect PRUNE1 function (Zollo M et.al .,2017). This variant has been reported to the ClinVar database as Pathogenic/Likely Pathogenic. The p.Asp106Asn variant is novel (not in any individuals) in 1000 Genomes and allele frequency of 0.00005177% is reported in gnomAD. The amino acid Asp at position 106 is changed to a Asn changing protein sequence and it might alter its composition and physico-chemical properties. For these reasons, this variant has been classified as Pathogenic. -

This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 106 of the PRUNE1 protein (p.Asp106Asn). This variant is present in population databases (rs773618224, gnomAD 0.02%). This missense change has been observed in individual(s) with PRUNE1-related neurodevelopmental conditions (PMID: 26539891, 28334956, 29797509). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 402131). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt PRUNE1 protein function with a negative predictive value of 80%. For these reasons, this variant has been classified as Pathogenic. -
