Genes affected

ENSG00000290217 (HGNC:):

SLC17A1 (HGNC:10929): (solute carrier family 17 member 1) Predicted to enable sialic acid transmembrane transporter activity. Involved in urate metabolic process and urate transport. Located in apical plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

H2BC1 (HGNC:18730): (H2B clustered histone 1) 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-dependent histone that is a testis/sperm-specific member of the histone H2B family. Transcripts from this gene contain a palindromic termination element. [provided by RefSeq, Aug 2015]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
