Genes affected

CSTF2T (HGNC:17086): (cleavage stimulation factor subunit 2 tau variant) Enables RNA binding activity. Predicted to be involved in pre-mRNA cleavage required for polyadenylation. Located in nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

CSTF2T links:

PRKG1 (HGNC:9414): (protein kinase cGMP-dependent 1) Mammals have three different isoforms of cyclic GMP-dependent protein kinase (Ialpha, Ibeta, and II). These PRKG isoforms act as key mediators of the nitric oxide/cGMP signaling pathway and are important components of many signal transduction processes in diverse cell types. This PRKG1 gene on human chromosome 10 encodes the soluble Ialpha and Ibeta isoforms of PRKG by alternative transcript splicing. A separate gene on human chromosome 4, PRKG2, encodes the membrane-bound PRKG isoform II. The PRKG1 proteins play a central role in regulating cardiovascular and neuronal functions in addition to relaxing smooth muscle tone, preventing platelet aggregation, and modulating cell growth. This gene is most strongly expressed in all types of smooth muscle, platelets, cerebellar Purkinje cells, hippocampal neurons, and the lateral amygdala. Isoforms Ialpha and Ibeta have identical cGMP-binding and catalytic domains but differ in their leucine/isoleucine zipper and autoinhibitory sequences and therefore differ in their dimerization substrates and kinase enzyme activity.

Ambry Genetics

Nov 30, 2021

The c.1322G>C (p.C441S) alteration is located in exon 1 (coding exon 1) of the CSTF2T gene. This alteration results from a G to C substitution at nucleotide position 1322, causing the cysteine (C) at amino acid position 441 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
