• HASPIN p.Pro8Leu

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 0P and 0B.

The NM_031965.2(HASPIN):​c.22_24delCCTinsTTG​(p.Pro8Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. It is difficult to determine the true allele frequency of this variant because it is of type MNV, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in the same amino acid substitution has been previously reported as Uncertain significance in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P8S) has been classified as Uncertain significance.

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]

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.

P2RX5 (HGNC:8536): (purinergic receptor P2X 5) The product of this gene belongs to the family of purinoceptors for ATP. This receptor functions as a ligand-gated ion channel. Alternative splicing results in multiple transcript variants. Read-through transcription also exists between this gene and the neighboring downstream gene, TAX1BP3 (Tax1 binding protein 3).
