Genes affected

TMEM204 (HGNC:14158): (transmembrane protein 204) C16ORF30 plays a role in cell adhesion and cellular permeability at adherens junctions (Kearsey et al., 2004 [PubMed 15206924]).[supplied by OMIM, Mar 2008]

TMEM204 links:

IFT140 (HGNC:29077): (intraflagellar transport 140) This gene encodes one of the subunits of the intraflagellar transport (IFT) complex A. Intraflagellar transport is involved in the genesis, resorption and signaling of primary cilia. The primary cilium is a microtubule-based sensory organelle at the surface of most quiescent mammalian cells, that receives signals from its environment, such as the flow of fluid, light or odors, and transduces those signals to the nucleus. Loss of the corresponding protein in mouse results in renal cystic disease. [provided by RefSeq, Jun 2012]

May 20, 2024

The c.173G>T (p.G58V) alteration is located in exon 1 (coding exon 1) of the TMEM204 gene. This alteration results from a G to T substitution at nucleotide position 173, causing the glycine (G) at amino acid position 58 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
