Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_013232.4(PDCD6):​c.167C>T​(p.Thr56Met) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T56K) has been classified as Uncertain significance.

Genes affected

PDCD6 (HGNC:8765): (programmed cell death 6) This gene encodes a calcium-binding protein belonging to the penta-EF-hand protein family. Calcium binding is important for homodimerization and for conformational changes required for binding to other protein partners. This gene product participates in T cell receptor-, Fas-, and glucocorticoid-induced programmed cell death. In mice deficient for this gene product, however, apoptosis was not blocked suggesting this gene product is functionally redundant. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and a pseudogene of this gene is also located on the short arm of chromosome 5.

PDCD6-AHRR (HGNC:54724): (PDCD6-AHRR readthrough (NMD candidate)) Predicted to enable calcium ion binding activity. [provided by Alliance of Genome Resources, Apr 2022]
