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]

Pathogenic, criteria provided, single submitter	clinical testing	Neuberg Centre For Genomic Medicine, NCGM	-	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. -

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 27, 2021	For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has been observed in individual(s) with PRUNE1-related neurodevelopmental conditions (PMID: 26539891, 28334956, 29797509). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 402131). This variant is present in population databases (rs773618224, ExAC 0.02%). This sequence change replaces aspartic acid with asparagine at codon 106 of the PRUNE1 protein (p.Asp106Asn). The aspartic acid residue is highly conserved and there is a small physicochemical difference between aspartic acid and asparagine. -
