Kallmann syndrome (KS) is a rare clinical and genetic heterogeneity disease, which is familial or sporadic. KS is known to have three patterns of inheritance: X linked recessive inheritance, autosomal dominant inheritance and rare autosomal recessive inheritance. Here, we report a sibling pedigree with autosomal dominant inheritance of KS, and we identified a novel heterozygous frameshift mutation c.299_300insCCGCAGACTCCGGCCTCTATGC (p.C101Rfs*17) in FGFR1 gene using whole-exome sequencing (WES). The mutation and affection status were cosegregated. The mutation is not present in the dbSNP, 1000 Genome, ExAC, and gnomAD databases. The discovery of this new mutation in the FGFR1 gene enriches the spectrum of FGFR1 mutations in patients with KS.Abbreviations: FGFR1: fibroblast growth factor receptor 1; HH: hypogonadotropic hypogonadism; KS: Kallmann syndrome; MRI: magnetic resonance imaging; WES: whole-exome sequencing.
