Description

This variant is denoted CDH1 c.337A>G at the cDNA level, p.Lys113Glu (K113E) at the protein level, and results in the change of a Lysine to a Glutamic Acid (AAA>GAA). This variant has been observed in co-occurrence with a pathogenic MSH6 variant, in one individual with endometrial cancer and a diagnosis of Lynch syndrome (Jori 2015). This variant has also been observed in at least one individual with non-syndromic orofacial cleft, with no specific information about cancer history (Vogelaar 2013). CDH1 Lys113Glu was not observed at a significant allele frequency in large population cohorts (Lek 2016). CDH1 Lys113Glu is located in the precursor sequence domain Brooks-WIlson 2004). In-silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function. Based on currently available evidence, it is unclear whether CDH1 Lys113Glu is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
