Genes affected

NUBP1 (HGNC:8041): (NUBP iron-sulfur cluster assembly factor 1, cytosolic) NUBP1 is a member of the NUBP/MRP subfamily of ATP-binding proteins (Nakashima et al., 1999 [PubMed 10486206]).[supplied by OMIM, Mar 2008]

NUBP1 links:

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.809A>G (p.D270G) alteration is located in exon 9 (coding exon 9) of the NUBP1 gene. This alteration results from a A to G substitution at nucleotide position 809, causing the aspartic acid (D) at amino acid position 270 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
