Genes affected

ZNF142 (HGNC:12927): (zinc finger protein 142) The protein encoded by this gene belongs to the Kruppel family of C2H2-type zinc finger proteins. It contains 31 C2H2-type zinc fingers and may be involved in transcriptional regulation. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jan 2013]

BCS1L (HGNC:1020): (BCS1 homolog, ubiquinol-cytochrome c reductase complex chaperone) This gene encodes a homolog of the S. cerevisiae bcs1 protein which is involved in the assembly of complex III of the mitochondrial respiratory chain. The encoded protein does not contain a mitochondrial targeting sequence but experimental studies confirm that it is imported into mitochondria. Mutations in this gene are associated with mitochondrial complex III deficiency and the GRACILE syndrome. Several alternatively spliced transcripts encoding two different isoforms have been described. [provided by RefSeq, Jan 2016]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.47).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.11 is higher than 0.05.
