Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_003367.4(USF2):c.271G>C(p.Gly91Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000776 in 1,288,768 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. G91S) has been classified as Uncertain significance.

Genes affected

USF2 (HGNC:12594): (upstream transcription factor 2, c-fos interacting) This gene encodes a member of the basic helix-loop-helix leucine zipper family of transcription factors. The encoded protein can activate transcription through pyrimidine-rich initiator (Inr) elements and E-box motifs and is involved in regulating multiple cellular processes.

Ambry Genetics

Oct 10, 2023

The c.271G>C (p.G91R) alteration is located in exon 4 (coding exon 4) of the USF2 gene. This alteration results from a G to C substitution at nucleotide position 271, causing the glycine (G) at amino acid position 91 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
