Description

Spondylometaphyseal Dysplasia, Kozlowski Type

In a patient with the Kozlowski type of spondylometaphyseal dysplasia (SMDK; 184252), Dai et al. (2010) identified heterozygosity for a c.2389G-A transition in exon 15 of the TRPV4 gene, resulting in a glu797-to-lys (E797K) substitution at an evolutionarily conserved residue in the cytoplasmic domain. The authors noted that this was the first SMDK patient to be reported with a mutation in exon 15, which otherwise appears to be a hotspot for mutations causing metatropic dysplasia (MTD; 156530).

Spondylometaphyseal Dysplasia, Maroteaux Type

In an adult woman with the Maroteaux type of spondyloepiphyseal dysplasia (184095), Nishimura et al. (2010) identified heterozygosity for the E797K mutation in the TRPV4 gene.

Metatropic Dysplasia

Camacho et al. (2010) identified a heterozygous E797K mutation in a patient with a mild form of metatropic dysplasia (MTD; 156530), with little or no scoliosis, mild platyspondyly, mild metaphyseal widening, and carpal ossification delay.
