Genetic Variant CITED4:p.Gly25Cys (chr1-40862055-C-A) – ACMG Classification: Likely_benign (-5 pts)

Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 0P and 5B. BP4BS2

The NM_133467.3(CITED4):c.73G>T(p.Gly25Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00004 in 1,324,692 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 (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G25V) has been classified as Uncertain significance.

Genes affected

CITED4 (HGNC:18696): (Cbp/p300 interacting transactivator with Glu/Asp rich carboxy-terminal domain 4) The protein encoded by this intronless gene belongs to the CITED family of transcriptional coactivators that bind to several proteins, including CREB-binding protein (CBP) and p300, via a conserved 32 aa C-terminal motif, and regulate gene transcription. This protein also interacts with transcription factor AP2 (TFAP2), and thus may function as a co-activator for TFAP2. Hypermethylation and transcriptional downregulation of this gene has been observed in oligodendroglial tumors with deletions of chromosomal arms 1p and 19q, and associated with longer recurrence-free and overall survival of patients with oligodendroglial tumors.

Collection Method: clinical testing

The c.73G>T (p.G25C) alteration is located in exon 1 (coding exon 1) of the CITED4 gene. This alteration results from a G to T substitution at nucleotide position 73, causing the glycine (G) at amino acid position 25 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
