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.

The PALB2 c.-10C>T variant has not been reported in individuals with PALB2-related conditions in the published literature. The frequency of this variant in the general population, 0.00013 (3/23874 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Based on the available information, we are unable to determine the clinical significance of this variant. -

The c.-10C>T alteration is located in the 5' untranslated region (5'UTR) of the PALB2 gene. This alteration consists of a C to T substitution nucleotides upstream from the first translated codon. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
