About this study

The aim of the CDH1-associated Blepharocheilodontic Syndrome (BCDS) registry is to better characterize the clinical features of this condition and exploring whether CDH1 variants linked to BCDS may also increase cancer risk.

Read the detailed description

Blepharocheilodontic Syndrome (BCDS) is a rare genetic disorder characterized by cleft lip and/or palate (CL/P), eyelid malformations, and features suggestive of ectodermal dysplasia. Variants in the CDH1 gene, which encodes the cell adhesion protein E-cadherin, have been implicated in BCDS. Functional studies have demonstrated that CDH1 plays a critical role in lip and palate development during embryogenesis (Ghoumid 2017; Figueiredo 2019).

In the hereditary cancer genetics community, CDH1 is more commonly associated with hereditary diffuse gastric and lobular breast cancer syndrome (DGLBC). CDH1 variants linked to DGLBC are typically truncating mutations, resulting in a null allele. In contrast, CDH1 variants observed in individuals with BCDS are often missense mutations located in the EC1-EC2 linker region (amino acids 254-257) or exon 9 donor splice site variants (e.g., c.1320G>T, c.1320+1G>A, c.1320+1G>T, c.1320+1G>C, c.1320+5G>A) (Ghoumid 2017; Kievit 2018).

Historically, it was believed that individuals with BCDS-associated CDH1 missense variants were not at increased risk for DGLBC-associated cancers. This assumption was based on the absence of reported cancer cases in published BCDS families and epidemiological data from the CDH1 ClinGen Variant Curation Expert Panel (VCEP), which suggested that missense variants may not confer elevated cancer risk (Ghoumid 2017; Kievit 2018; Lee 2018).

However, a 2020 case report by LeBlanc et al. described a family with a known BCDS-associated CDH1 missense variant (c.768T>A, p.N256K), in which a 37-year-old male developed diffuse gastric cancer. This report raised concerns about potential cancer risks in individuals with BCDS-associated CDH1 variants and prompted questions regarding the need for endoscopic screening and other surveillance measures.

Currently, data regarding cancer risk in individuals with CDH1 variants and the BCDS phenotype are limited. The condition is rare, and affected individuals are often identified through exome sequencing due to multiple congenital anomalies. The interpretation of familial cancer risk is further complicated by a high rate of de novo mutations and limited family history.

To address these gaps, this registry aims to establish a centralized, international cohort of individuals with CDH1-associated BCDS. The goal is to better characterize the genotype-phenotype correlations, define the clinical spectrum, and assess the potential cancer risks associated with these variants.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Comprehensive characterization of the clinical phenotype associated with CDH1-associated blepharocheilodontic syndrome (BCDS)

    Reporting of currently known clinical characteristics of CDH1-associated Blepharocheilodontic Syndrome (BCDS), including but not limited to cleft lip and/or palate, eyelid anomalies, dental abnormalities, webbed toes, and imperforate anus. The study will also document additional clinical features that may not have been previously reported in the literature, with the goal of expanding the phenotypic understanding of this rare condition.

    Measured: 5 years

Secondary outcomes (1)
  1. Development of evidence-based cancer surveillance recommendations for individuals with CDH1-assocaited blepharocheilodontic syndrome.

    Personal and family cancer history will be collected and reviewed annually to evaluate potential cancer risks associated with CDH1 variants in individuals with blepharocheilodontic syndrome (BCDS). For participants who are of appropriate age and undergoing endoscopic surveillance as part of their routine medical care, relevant endoscopic and pathology reports will be obtained and analyzed to assess the presence and prevalence of signet ring cells, a hallmark of diffuse gastric cancer. This comprehensive data collection will support efforts to develop evidence-based cancer surveillance recommendations tailored to individuals with CDH1-associated BCDS.

    Measured: 10 years

Individual data sharing
Yes: Individual participant data will not be broadly shared. However, external requests for data access may be considered for use in downstream research protocols. All such requests must include an IRB-approved protocol and a formal application for data use. The BCDS Registry Advisory Board, comprising the Principal Investigator and at least one co-investigator, will review applications based on scientific merit and relevance, with input from a statistician as needed. For approved requests, data will be shared via a secure "data push," typically involving export from REDCap to a coded-limited file format. The individual responsible for data transfer will be certified as an honest broker under the OSUWMC Honest Broker Protocol. All studies using registry data will be conducted under separate IRB oversight.
