Genes affected
H2BW2 (HGNC:27867): (H2B.W histone 2) 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 encodes a replication-independent histone that is a member of the H2B histone family. [provided by RefSeq, Nov 2015]

The c.275T>C (p.I92T) alteration is located in exon 1 (coding exon 1) of the H2BFM gene. This alteration results from a T to C substitution at nucleotide position 275, causing the isoleucine (I) at amino acid position 92 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
