In a 23-year-old proband and his affected mother in a consanguineous Iranian family with LADD syndrome (149730), Talebi et al. (2017) identified a heterozygous c.1882G-A transition in exon 14 of the FGFR3 gene, resulting in an asp628-to-asn (D628N) substitution at a highly conserved residue in the cytoplasmic tyrosine kinase domain. The mutation, which was found by next-generation sequencing and confirmed by Sanger sequencing, was not present in the unaffected father or in 400 control chromosomes. No functional studies were reported.
