Abstract:
Protein tyrosine phosphatases, together with protein tyrosine kinases, control many molecular signaling steps that control life at cellular and organismal levels. Impairing alterations in the genes encoding the involved proteins is expected to profoundly affect the quality of life-if compatible with life at all. Here, we review the current knowledge on the effects of germline variants that have been reported for genes encoding a subset of the protein tyrosine phosphatase superfamily; that of the thirty seven classical members. The conclusion must be that the newest genome research tools produced an avalanche of data that suggest 'guilt by association' for individual genes to specific disorders. Future research should face the challenge to investigate these accusations thoroughly and convincingly, to reach a mature genotype-phenotype map for this intriguing protein family.
Insights
Germline variants in protein tyrosine phosphatase genes are linked to various disorders, according to new genome research. Further studies are needed to confirm these associations and map gene-phenotype relationships.
Area of Science:
- Biochemistry
- Genetics
- Molecular Biology
Background:
- Protein tyrosine phosphatases (PTPs) and kinases are crucial for cellular signaling.
- Genetic alterations in PTPs can significantly impact health and survival.
Purpose of the Study:
- To review the effects of germline variants in a subset of PTP superfamily genes.
- To assess the current understanding of genotype-phenotype correlations in PTPs.
Main Methods:
- Literature review of reported germline variants in PTP genes.
- Analysis of data from recent genome research tools.
Main Results:
- Genome research has generated extensive data suggesting associations between specific PTP genes and disorders.
- These findings often rely on 'guilt by association' due to large-scale data.
Conclusions:
- The current data implicates numerous PTP genes in various diseases.
- Future research must rigorously validate these associations to establish definitive genotype-phenotype maps for PTPs.
