FBLN7 and breast neoplasm: The fibulin family is a group of eight ECM glycoproteins involved in tissue remodeling, cell‐matrix interactions, and the conversion of cell phenotypes.[9, 10] Fibulin 7 (FBLN7) is a newly identified member of the fibulin family and is expressed in the eye, placenta, cartilage, teeth, blood vessels, and other vital tissues.[11] It is involved in multiple diseases and developmental anomalies,[12] such as 2q13 deletion syndrome, glioblastoma, renal tubular calcification, and breast tumors.
