What's a GeneRIF?

TMEM38B mutations could lead to a rare form of OI, with an autosomal recessive pattern of inheritance. We identified two novel mutations (c.455-7T>G in intron 3 and c.507G>A in exon 4) in TMEM38B in three Chinese children with OI. The two mutations created a new acceptor splice site (p.R151_G152insVL) and a novel downstream termination codon (p.W169X), respectively

TMEM38B is a novel candidate gene for autosomal recessive Osteogenesis imperfecta (OI). Future studies are needed to explore fully the contribution of this gene to autosomal recessive Osteogenesis imperfecta (OI) in other populations.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
