This gene has been found to be expressed in WT and developing fetal kidney [36] while SALL4 deletions are a common cause of Okihiro, acro-renal-ocular, and SALL4-related Holt-Oram syndromes [37], all of which associated with renal morphological malformations rather than WT. Here, SALL4 is linked to Holt-Oram syndrome.
