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]

MINDY1 (HGNC:25648): (MINDY lysine 48 deubiquitinase 1) Enables K48-linked polyubiquitin modification-dependent protein binding activity; Lys48-specific deubiquitinase activity; and cysteine-type carboxypeptidase activity. Predicted to be involved in protein K48-linked deubiquitination. Located in nuclear body. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Pathogenic. The variant received 12 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. There are 21 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-151008634-T-TGGAGG is Pathogenic according to our data. Variant chr1-151008634-T-TGGAGG is described in ClinVar as Pathogenic. ClinVar VariationId is 521739.Status of the report is criteria_provided_single_submitter, 1 stars.
