Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 0P and 2B. BP4 BS2_Supporting

The NM_006079.5(CITED2):​c.581G>A​(p.Gly194Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000133 in 1,432,608 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. G194G) has been classified as Benign.

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]

ENSG00000226571 (HGNC:):

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.28551883).
• BS2: High AC in GnomAdExome4 at 19 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

The c.581G>A (p.G194D) 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 581, causing the glycine (G) at amino acid position 194 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
