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]

Collection Method: clinical testing

The c.154C>T (p.L52F) alteration is located in exon 2 (coding exon 2) of the PDCD6 gene. This alteration results from a C to T substitution at nucleotide position 154, causing the leucine (L) at amino acid position 52 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
