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.170C>T (p.P57L) alteration is located in exon 1 (coding exon 1) of the GSG2 gene. This alteration results from a C to T substitution at nucleotide position 170, causing the proline (P) at amino acid position 57 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
