%0 Journal Article %T A novel S269C mutation in fibroblast growth factor receptor 3 in a Japanese child with hypochondroplasia %J - %D 2018 %R https://doi.org/10.1038/s41439-018-0001-2 %X Functionally activating mutations in fibroblast growth factor receptor 3 (FGFR3) can cause four types of autosomal dominant skeletal dysplasia with short-limbed dwarfism that include the mildest phenotype, hypochondroplasia (HCH). A novel mutation (c.805A>T, p.S269C) was identified in a Japanese infant with HCH through direct sequencing of all FGFR3 exons and exon/intron boundaries. This mutation creates an additional cysteine residue in the extracellular region of FGFR3 that results in the functional activation of FGFR3 %U https://www.nature.com/articles/s41439-018-0001-2
