Genes affected

PDCD10 (HGNC:8761): (programmed cell death 10) This gene encodes an evolutionarily conserved protein associated with cell apoptosis. The protein interacts with the serine/threonine protein kinase MST4 to modulate the extracellular signal-regulated kinase (ERK) pathway. It also interacts with and is phosphoryated by serine/threonine kinase 25, and is thought to function in a signaling pathway essential for vascular developent. Mutations in this gene are one cause of cerebral cavernous malformations, which are vascular malformations that cause seizures and cerebral hemorrhages. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 3-167695690-G-A is Pathogenic according to our data. Variant chr3-167695690-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 468329.Status of the report is criteria_provided_single_submitter, 1 stars.

For these reasons, this variant has been classified as Pathogenic. While this particular variant has not been reported in the literature, loss-of-function variants in PDCD10 are known to be pathogenic (PMID: 15543491, 23801932). This sequence change creates a premature translational stop signal at codon 101 (p.Gln101*) of the PDCD10 gene. It is expected to result in an absent or disrupted protein product. -
