Genes affected
PPP1R13B (HGNC:14950): (protein phosphatase 1 regulatory subunit 13B) This gene encodes a member of the ASPP (apoptosis-stimulating protein of p53) family of p53 interacting proteins. The protein contains four ankyrin repeats and an SH3 domain involved in protein-protein interactions. ASPP proteins are required for the induction of apoptosis by p53-family proteins. They promote DNA binding and transactivation of p53-family proteins on the promoters of proapoptotic genes. Expression of this gene is regulated by the E2F transcription factor.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 04, 2024The c.3254G>A (p.R1085Q) alteration is located in exon 17 (coding exon 17) of the PPP1R13B gene. This alteration results from a G to A substitution at nucleotide position 3254, causing the arginine (R) at amino acid position 1085 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
