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]

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.

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0024497807).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.0996 is higher than 0.05.
