Genes affected

SLC25A2 (HGNC:22921): (solute carrier family 25 member 2) This intronless gene encodes a protein that localizes to the mitochondrial inner membrane and likely functions as a transporter of small molecules such as ornithine. This gene is located between the protocadherin beta and gamma gene clusters on chromosome 5. [provided by RefSeq, Dec 2014]

SLC25A2 links:

TAF7 (HGNC:11541): (TATA-box binding protein associated factor 7) The intronless gene for this transcription coactivator is located between the protocadherin beta and gamma gene clusters on chromosome 5. The protein encoded by this gene is a component of the TFIID protein complex, a complex which binds to the TATA box in class II promoters and recruits RNA polymerase II and other factors. This particular subunit interacts with the largest TFIID subunit, as well as multiple transcription activators. The protein is required for transcription by promoters targeted by RNA polymerase II.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.689T>A (p.V230E) alteration is located in exon 1 (coding exon 1) of the SLC25A2 gene. This alteration results from a T to A substitution at nucleotide position 689, causing the valine (V) at amino acid position 230 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
