Saethre-Chotzen syndrome (SCS) is caused by mutation in the TWIST1 gene (MIM.601622).
A phenotype of SCS has been described with a mutation in the FGFR2 gene (MIM.176943).
Twist-1 may act as a key regulator of metastasis and that the gene is overexpressed in subsets of sporadic human breast cancers.
Muenke syndrome (MIM.602849)
- Muenke syndrome is caused by a mutation in the FGFR3 gene (P250R) has a similar overlapping phenotype to SCS.
