Genes affected

CITED2 (HGNC:1987): (Cbp/p300 interacting transactivator with Glu/Asp rich carboxy-terminal domain 2) The protein encoded by this gene inhibits transactivation of HIF1A-induced genes by competing with binding of hypoxia-inducible factor 1-alpha to p300-CH1. Mutations in this gene are a cause of cardiac septal defects. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, May 2012]

(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=0.11277273).

The c.562G>A (p.G188S) alteration is located in exon 2 (coding exon 1) of the CITED2 gene. This alteration results from a G to A substitution at nucleotide position 562, causing the glycine (G) at amino acid position 188 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
