Summary: This gene encodes a transmembrane protein with four predicted transmembrane domains. The protein is associated with a subpopulation of vesicular organelles corresponding to early endosomal structures, with the Golgi, and with lysosomes, and may participate in protein trafficking between these structures. Mutations in this gene and several other genes cause pheochromocytomas. Alternatively spliced transcript variants encoding the same protein have been identified. [provided by RefSeq, Aug 2022]

n the present cases, the clinical picture does not seem to be very different from heterozygous TMEM127 mutation carriers, except for a relatively large tumor size and more pronounced plasma metanephrine concentration. It is unclear whether the mental retardation is causally related to homozygosity of the TMEM127 mutations.
Title: Homozygous TMEM127 mutations in 2 patients with bilateral pheochromocytomas.
We found that under nutrient-rich conditions TMEM127 expression reduces mTORC1 recruitment to Rags. In addition, TMEM127 interacts with LAMTOR in an amino acid-dependent manner and decreases the LAMTOR1-vATPase association, while TMEM127-vATPase binding requires intact lysosomal acidification but is amino acid independent

Hereditary pheochromocytoma / paraganglioma associated with TMEM127 gene mutations has more aggressive course,bilateral adrenal involvement, higher recurrence rate, younger age at disease manifestations.
Title: [Hereditary pheochromocytoma-associated syndromes. Part 1].
We report the first case of an individual with both a pheochromocytoma and a multilocular clear cell renal cell carcinoma driven by a novel germline mutation in the TMEM127 gene, with a sibling and 2 sons with the same mutation.

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.
