Genes affected

HIRA (HGNC:4916): (histone cell cycle regulator) This gene encodes a histone chaperone that preferentially places the variant histone H3.3 in nucleosomes. Orthologs of this gene in yeast, flies, and plants are necessary for the formation of transcriptionally silent heterochomatin. This gene plays an important role in the formation of the senescence-associated heterochromatin foci. These foci likely mediate the irreversible cell cycle changes that occur in senescent cells. It is considered the primary candidate gene in some haploinsufficiency syndromes such as DiGeorge syndrome, and insufficient production of the gene may disrupt normal embryonic development.

The c.2686T>C (p.S896P) alteration is located in exon 23 (coding exon 23) of the HIRA gene. This alteration results from a T to C substitution at nucleotide position 2686, causing the serine (S) at amino acid position 896 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
