Background: Craniosynostosis (CS) syndrome is an autosomal dominant condition classically combining craniosynostosis and non-syndromic craniosynostosis with digital anomalies of the hands and feet. The majority of cases are caused by heterozygous mutations in the third immunoglobulin-like domain (IgIII) of FGFR2, whilst a larger number of cases can be attributed to mutations outside this region of the protein. Aims: To find out the FGFR1, FGFR2, FGFR3 and FGFR4 gene in craniosynostosis syndrome. Settings and Design: A hospital based prospective study. Materials and Methods: Prospective analysis of clinical records of patients registered in CS clinic from December 2007 to January 2015 was done in patients between 4 months to 13 years of age. We have performed genetic findings in a three generation Indian family with Craniosynostosis syndrome. Results: We report for the first time the clinical and genetic findings in a three generation Indian family with Craniosynostosis syndrome caused by a heterozygous missense mutation, Thr 392 Thr and ser 311 try, located in the IgII domain of FGFR2. FGFR 3 and 4 gene basis syndrome was eponymously named. Genetic analysis demonstrated that 51/56 families to be unrelated. In FGFR3 gene 10/TM location of 1172 the nucleotide changes C>A, Ala 391 Glu 19/56 and Exon-19, 5q35.2 at conserved linker region the changes occurred pro 246 Arg in 25/56 families. Conclusions: Independent genetic origins, but phenotypic similarities in the 51 families add to the evidence supporting the theory of selfish spermatogonial selective advantage for this rare gain-of-function FGFR2 mutation.
