Vegf interacted with Tbx1as Tbx1 velocardiofcaial was reduced in Vegfdeficient embryos and knocked-down Vegf levels enhanced the pharyngeal arch artery defects induced by Tbx1 knockdown in zebrafish.
The ordered markers were used to examine the 2 separated copies of chromosome 22 in the somatic hybrid cell lines. An anomalously oriented ascending aorta may cause severe left main bronchus obstruction secondary to external compression. Sixty percent of patients had no visceral anomalies.
