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

Our verdict: Likely_benign. The variant received -5 ACMG points.

• BS1: Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.00299 (454/152046) while in subpopulation AMR AF = 0.00504 (77/15272). AF 95% confidence interval is 0.00429. There are 2 homozygotes in GnomAd4. There are 210 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
• BS2: High AC in GnomAd4 at 454 AD gene.
