Genes affected

MTX1 (HGNC:7504): (metaxin 1) Predicted to be involved in mitochondrion organization. Part of MIB complex and SAM complex. [provided by Alliance of Genome Resources, Apr 2022]

MTX1 links:

THBS3 (HGNC:11787): (thrombospondin 3) The protein encoded by this gene belongs to the thrombospondin family. Thrombospondin family members are adhesive glycoproteins that mediate cell-to-cell and cell-to-matrix interactions. This protein forms a pentameric molecule linked by a single disulfide bond. This gene shares a common promoter with metaxin 1. Alternate splicing results in coding and non-coding transcript variants. [provided by RefSeq, Nov 2011]
