Summaries for CRELD1 Gene

Entrez Gene Summary for CRELD1 Gene

  • This gene encodes a member of a subfamily of epidermal growth factor-related proteins. The encoded protein is characterized by a cysteine-rich with epidermal growth factor-like domain. This protein may function as a cell adhesion molecule. Mutations in this gene are the cause of atrioventricular septal defect. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Apr 2010]

  • Atrioventricular septal defect 2 (AVSD2) [MIM:606217]: A congenital heart malformation characterized by a common atrioventricular junction coexisting with deficient atrioventricular septation. The complete form involves underdevelopment of the lower part of the atrial septum and the upper part of the ventricular septum; the valve itself is also shared. A less severe form, known as ostium primum atrial septal defect, is characterized by separate atrioventricular valvar orifices despite a common junction. {ECO:0000269 PubMed:12632326, ECO:0000269 PubMed:15857420}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
