Genes affected

PPP1R37 (HGNC:27607): (protein phosphatase 1 regulatory subunit 37) Predicted to enable protein phosphatase inhibitor activity. Predicted to be involved in negative regulation of catalytic activity. [provided by Alliance of Genome Resources, Apr 2022]

PPP1R37 links:

MARK4 (HGNC:13538): (microtubule affinity regulating kinase 4) This gene encodes a member of the microtubule affinity-regulating kinase family. These protein kinases phosphorylate microtubule-associated proteins and regulate the transition between stable and dynamic microtubules. The encoded protein is associated with the centrosome throughout mitosis and may be involved in cell cycle control. Expression of this gene is a potential marker for cancer, and the encoded protein may also play a role in Alzheimer's disease. Pseudogenes of this gene are located on both the short and long arm of chromosome 3. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

Ambry Genetics

Oct 29, 2021

The c.35C>T (p.P12L) alteration is located in exon 1 (coding exon 1) of the PPP1R37 gene. This alteration results from a C to T substitution at nucleotide position 35, causing the proline (P) at amino acid position 12 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
