Genes affected

HMGN4 (HGNC:4989): (high mobility group nucleosomal binding domain 4) The protein encoded by this gene, a member of the HMGN protein family, is thought to reduce the compactness of the chromatin fiber in nucleosomes, thereby enhancing transcription from chromatin templates.

The c.130G>C (p.A44P) alteration is located in exon 2 (coding exon 1) of the HMGN4 gene. This alteration results from a G to C substitution at nucleotide position 130, causing the alanine (A) at amino acid position 44 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
