Genes affected

H1-0 (HGNC:4714): (H1.0 linker histone) Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Nucleosomes consist of approximately 146 bp of DNA wrapped around a histone octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4). The chromatin fiber is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures. This gene is intronless and encodes a replication-independent histone that is a member of the histone H1 family. [provided by RefSeq, Oct 2015]

The c.230C>G (p.T77S) alteration is located in exon 1 (coding exon 1) of the H1F0 gene. This alteration results from a C to G substitution at nucleotide position 230, causing the threonine (T) at amino acid position 77 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
