The fibulin-1 gene (FBLN1) is located on human chromosome 22 and on mouse chromosome 15.

Abstract

Fibulin-1 is a calcium-binding glycoprotein present in the extracellular matrix and in the serum. The gene coding for fibulin-1 (FBLN1) was located by in situ hybridization of 3H-labeled cDNA probes to human and mouse metaphase chromosomes. The gene was assigned to the q13.2-q13.3 region of human chromosome 22 and to the E-F band of mouse chromosome 15. This finding extends the evolutionary conservation between human chromosome 22 and mouse chromosome 15.
