Genes affected

PARD3B (HGNC:14446): (par-3 family cell polarity regulator beta) Predicted to enable phosphatidylinositol binding activity. Predicted to be involved in several processes, including establishment of cell polarity; establishment of centrosome localization; and establishment or maintenance of epithelial cell apical/basal polarity. Located in cell junction. Part of protein-containing complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

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

• BP4: Computational evidence support a benign effect (MetaRNN=1.5535625E-6).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.777 is higher than 0.05.
