The present study examined 58 members of a Kallmann syndrome family and investigated whether there are fibroblast growth factor receptor 1 (FGFR1) gene mutations in this family.Genomic DNA from the proband and family members was subjected to PCR to amplify 18 exons of FGFR1,and the amplified products were sequenced to identify potential mutations.MRI of the olfactory bulb region was performed on suspected subjects.The patient and his father were diagnosed with Kallmann syndrome.A polymorphic site was found at 39542,with the proband and his parents being heterozygous (guanine + cytosine).However,healthy controls and the other members of this family were homozygous for guanine at this position.
