Genes affected

ATF5 (HGNC:790): (activating transcription factor 5) Enables several functions, including DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II transcription regulatory region sequence-specific DNA binding activity; and tubulin binding activity. Involved in several processes, including fat cell differentiation; regulation of cell cycle process; and regulation of transcription, DNA-templated. Located in centrosome; cytosol; and nucleoplasm.

The c.305C>G (p.A102G) alteration is located in exon 4 (coding exon 2) of the ATF5 gene. This alteration results from a C to G substitution at nucleotide position 305, causing the alanine (A) at amino acid position 102 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
