However, recent reports have highlighted the more common milder presentation which has for cardinal features developmental delay, particularly in speech, neonatal hypotonia, relative macrocephaly, dysmorphic facial features, severe constipation, and few if any congenital malformations. Thus far, five separate loci have been identified on the X chromosome but attempts at finding the responsible gene have not yet been successful. Given that one putative FG locus (FGS2) is situated at Xq28, which is the location of the <jats:italic>Filamin A<\/jats:italic> gene (<jats:italic>FLNA<\/jats:italic>), and that a <jats:italic>Filamin A<\/jats:italic> mutation was reported in a boy with facial dysmorphism and constipation, it was hypothesized that <jats:italic>Filamin A<\/jats:italic> mutations could be one cause of FG syndrome. Indeed, a previously unreported <jats:italic>FLNA<\/jats:italic> missense mutation (P1291L) was detected in our patient with FG syndrome, thus supporting this hypothesis and indicating that FG syndrome could now be added to the list of <jats:italic>Filamin A<\/jats:italic>\u2010related disorders. <jats:italic>Filamin A<\/jats:italic> studies in other children with FG syndrome would help to confirm this association. \u00a9 2007 Wiley\u2010Liss,
