The mouse cartilage matrix protein gene (Crtm) was isolated from a cosmid library using a mouse Crtm cDNA fragment as probe. Crtm spans 12.2 kb from the start of translation to the polyadenylation signal sequence and comprises eight exons. Sequencing of the 1.9 kb 5' flanking region revealed a TATA-like box 72 bp upstream from the initiator Met codon as well as several cis-acting motifs known to bind eukaryotic transcription factors. Analysis of the exon-intron junctions demonstrated that the last intron does not follow the gt/ag rule but belongs to the minor class of pre-mRNA introns that contain "at" and "ac" at their 5'and 3' ends, respectively. Single-strand conformation polymorphism analysis was used to map Crtm to the distal part of chromosome 4 between the microsatellite markers D4Mit16 and D4Mit339. Achodroplasia (cn), a recessive skeletal disorder in mice, has already been mapped to this region. Immunostaining for CMP and sequence of Crtm in cn/cn mice failed to reveal any disease-specific mutations, suggesting that mutations in Crtm do not cause achondroplasia.

D007438 Introns Sequences of DNA in the genes that are located between the EXONS. They are transcribed along with the exons but are removed from the primary gene transcript by RNA SPLICING to leave mature RNA. Some introns code for separate genes.

D008099 Liver A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances. Livers
D008810 Mice, Inbred C57BL One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D000130 Achondroplasia An autosomal dominant disorder that is the most frequent form of short-limb dwarfism. Affected individuals exhibit short stature caused by rhizomelic shortening of the limbs, characteristic facies with frontal bossing and mid-face hypoplasia, exaggerated lumbar lordosis, limitation of elbow extension, GENU VARUM, and trident hand.
