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.

Ambry Genetics

Nov 14, 2024

The c.109C>T (p.P37S) alteration is located in exon 2 (coding exon 1) of the HMGN4 gene. This alteration results from a C to T substitution at nucleotide position 109, causing the proline (P) at amino acid position 37 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
