FGFR2 and chronic primary adrenal insufficiency: Conditional deletion of both isoforms of Fgfr2 from steroidogenic tissue also leads to adrenal hypoplasia (Kim et al., 2007) and global hemizygous deletion of exon IIIc of Fgfr2 does not appear to have any gross effect on adrenal development, unlike on the development of other visceral organs (Hajihosseini et al., 2001).
