Genes affected

HASPIN (HGNC:19682): (histone H3 associated protein kinase) Enables ATP binding activity and histone kinase activity (H3-T3 specific). Involved in histone H3-T3 phosphorylation involved in chromosome passenger complex localization to kinetochore; intracellular signal transduction; and mitotic sister chromatid cohesion. Located in centrosome; nucleoplasm; and spindle. [provided by Alliance of Genome Resources, Apr 2022]

HASPIN links:

ITGAE (HGNC:6147): (integrin subunit alpha E) Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. This gene encodes an I-domain-containing alpha integrin that undergoes post-translational cleavage in the extracellular domain, yielding disulfide-linked heavy and light chains. In combination with the beta 7 integrin, this protein forms the E-cadherin binding integrin known as the human mucosal lymphocyte-1 antigen. This protein is preferentially expressed in human intestinal intraepithelial lymphocytes (IEL), and in addition to a role in adhesion, it may serve as an accessory molecule for IEL activation.

The c.146G>A (p.S49N) alteration is located in exon 1 (coding exon 1) of the GSG2 gene. This alteration results from a G to A substitution at nucleotide position 146, causing the serine (S) at amino acid position 49 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
