Genes affected

H2AC15 (HGNC:4726): (H2A clustered histone 15) Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which approximately 146 bp of DNA is wrapped in repeating units, called nucleosomes. The linker histone, H1, interacts with linker DNA between nucleosomes and functions in the compaction of chromatin into higher order structures. This gene is intronless and encodes a replication-dependent histone that is a member of the histone H2A family. Transcripts from this gene lack polyA tails but instead contain a palindromic termination element. This gene is found in the small histone gene cluster on chromosome 6p22-p21.3.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.5C>T (p.S2L) alteration is located in exon 1 (coding exon 1) of the HIST1H2AK gene. This alteration results from a C to T substitution at nucleotide position 5, causing the serine (S) at amino acid position 2 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
