Genes affected

PPP1R13L (HGNC:18838): (protein phosphatase 1 regulatory subunit 13 like) IASPP is one of the most evolutionarily conserved inhibitors of p53 (TP53; MIM 191170), whereas ASPP1 (MIM 606455) and ASPP2 (MIM 602143) are activators of p53.[supplied by OMIM, Mar 2008]

PPP1R13L Gene-Disease associations (from GenCC):

• arrhythmogenic cardiomyopathy with variable ectodermal abnormalities

  Inheritance: AR Classification: DEFINITIVE Submitted by: Ambry Genetics
• dilated cardiomyopathy

  Inheritance: AR Classification: DEFINITIVE Submitted by: G2P

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.78).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.099 is higher than 0.05.
