Genes affected

PALB2 (HGNC:26144): (partner and localizer of BRCA2) This gene encodes a protein that may function in tumor suppression. This protein binds to and colocalizes with the breast cancer 2 early onset protein (BRCA2) in nuclear foci and likely permits the stable intranuclear localization and accumulation of BRCA2. [provided by RefSeq, Jul 2008]

DCTN5 (HGNC:24594): (dynactin subunit 5) This gene encodes a subunit of dynactin, a component of the cytoplasmic dynein motor machinery involved in minus-end-directed transport. The encoded protein is a component of the pointed-end subcomplex and is thought to bind membranous cargo. A pseudogene of this gene is located on the long arm of chromosome 1. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jan 2011]

ACMG classification

Our verdict: Benign. The variant received -11 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.44).
• BP6: Variant 16-23641315-C-G is Benign according to our data. Variant chr16-23641315-C-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 126571.
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0059 (899/152344) while in subpopulation NFE AF = 0.00735 (500/68034). AF 95% confidence interval is 0.00682. There are 6 homozygotes in GnomAd4. There are 500 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 6 AR,AD gene
