Genes affected

TRPT1 (HGNC:20316): (tRNA phosphotransferase 1) Predicted to enable tRNA 2'-phosphotransferase activity. Predicted to be involved in tRNA splicing, via endonucleolytic cleavage and ligation. Predicted to act upstream of or within regulation of protein kinase activity. [provided by Alliance of Genome Resources, Apr 2022]

TRPT1 links:

FERMT3 (HGNC:23151): (FERM domain containing kindlin 3) Kindlins are a small family of proteins that mediate protein-protein interactions involved in integrin activation and thereby have a role in cell adhesion, migration, differentiation, and proliferation. The protein encoded by this gene has a key role in the regulation of hemostasis and thrombosis. This protein may also help maintain the membrane skeleton of erythrocytes. Mutations in this gene cause the autosomal recessive leukocyte adhesion deficiency syndrome-III (LAD-III). Alternative splicing results in multiple transcript variants encoding distinct isoforms.

The c.732G>T (p.K244N) alteration is located in exon 8 (coding exon 7) of the TRPT1 gene. This alteration results from a G to T substitution at nucleotide position 732, causing the lysine (K) at amino acid position 244 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
