Prenatal diagnosis of short-rib polydactyly syndrome type III or short-rib thoracic dysplasia 3 with or without polydactyly (SRTD3) associated with compound heterozygous mutations in DYNC2H1 in a fetus.
Using targeted exome sequencing of 226 known genes implicated in inherited skeletal dysplasia, we identified compound heterozygous mutations in the DYNC2H1 gene in the fetus with short rib-polydactyly syndrome, type III (SRPS III), c.1151 C>T(p.Ala384Val) and c.4351 C>T (p.Gln1451*), which were inherited from paternally and maternally, respectively.
Here, we report novel compound heterozygous mutations in DYNC2H1 (p.E1894fsX10 and p.R3004C) in a patient with typical short-rib polydactyly syndrome type III phenotype.
