Genes affected

EXOC4 (HGNC:30389): (exocyst complex component 4) The protein encoded by this gene is a component of the exocyst complex, a multiple protein complex essential for targeting exocytic vesicles to specific docking sites on the plasma membrane. Though best characterized in yeast, the component proteins and functions of exocyst complex have been demonstrated to be highly conserved in higher eukaryotes. At least eight components of the exocyst complex, including this protein, are found to interact with the actin cytoskeletal remodeling and vesicle transport machinery. The complex is also essential for the biogenesis of epithelial cell surface polarity. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.86).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0209 (3187/152300) while in subpopulation NFE AF= 0.0316 (2153/68032). AF 95% confidence interval is 0.0305. There are 44 homozygotes in gnomad4. There are 1502 alleles in male gnomad4 subpopulation. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 45 AR gene
