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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2023The c.64C>A (p.H22N) alteration is located in exon 2 (coding exon 2) of the USF2 gene. This alteration results from a C to A substitution at nucleotide position 64, causing the histidine (H) at amino acid position 22 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
