Genes affected

ZBED6 (HGNC:33273): (zinc finger BED-type containing 6) The protein encoded by this transposon-derived intronless gene is a transcriptional repressor that binds to the consensus sequence 5'-GCTCGC-3'. The encoded protein has been shown to repress IGF2 transcription. This gene is located within the first intron of the ZC3H11A gene. [provided by RefSeq, Jul 2016]

ZC3H11A (HGNC:29093): (zinc finger CCCH-type containing 11A) Enables RNA binding activity. Involved in poly(A)+ mRNA export from nucleus. Colocalizes with transcription export complex. [provided by Alliance of Genome Resources, Apr 2022]

ZC3H11A (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.079271555).

Ambry Genetics

Dec 13, 2022

The c.1183C>G (p.Q395E) alteration is located in exon 1 (coding exon 1) of the ZBED6 gene. This alteration results from a C to G substitution at nucleotide position 1183, causing the glutamine (Q) at amino acid position 395 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
