RMRP gene sequence analysis confirms a cartilage‐hair hypoplasia variant with only skeletal manifestations and reveals a high density of single‐nucleotide polymorphisms

Abstract
Mutations in the RMRP gene that codes for an RNA subunit of the MRP RNAse complex are the cause of cartilage‐hair hypoplasia (CHH; MIM 250250). We tested the hypothesis that recessive metaphyseal dys...
