Genes affected

TVP23A (HGNC:20398): (trans-golgi network vesicle protein 23 homolog A) This gene encodes a membrane protein associated with the Golgi apparatus, which plays a crucial role in intracellular vesicular transport. The encoded protein is likely associated with the late (trans) Golgi compartments, which are involved in the delivery of secretory and membrane proteins to the endosome, lysosome or the plasma membrane. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

The c.636G>C (p.Q212H) alteration is located in exon 7 (coding exon 7) of the TVP23A gene. This alteration results from a G to C substitution at nucleotide position 636, causing the glutamine (Q) at amino acid position 212 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
