PALB2 c.2257C>T truncating variant is a Greek founder and is associated with high breast cancer risk.

PALB2 loss-of-function variants play an important role in breast, pancreatic and possibly, ovarian and gastric cancer susceptibility. Their frequency can be influenced by founder effects, already described in some populations. Herein, we have assessed the possible founder effect of PALB2 c.

Mutational analysis of TSC1 and TSC2 genes in Tuberous Sclerosis Complex patients from Greece.

Tuberous sclerosis complex (TSC) is a rare autosomal dominant disorder causing benign tumors in the brain and other vital organs. The genes implicated in disease development are TSC1 and TSC2. Here, we have performed mutational analysis followed by a genotype-phenotype correlation study based on the clinical characteristics of the affected individuals.
