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.

ACMG classification

Verdict is Benign. Variant got -9 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.81).
• BP6: Variant 16-23603112-T-G is Benign according to our data. Variant chr16-23603112-T-G is described in ClinVar as [Likely_benign]. Clinvar id is 126568.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr16-23603112-T-G is described in Lovd as [Benign].
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00123 (188/152338) while in subpopulation AFR AF= 0.00438 (182/41586). AF 95% confidence interval is 0.00386. There are 0 homozygotes in gnomad4. There are 91 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
