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]

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.

MARK4 Gene-Disease associations (from GenCC):

• neurodevelopmental disorder

  Inheritance: AD Classification: LIMITED Submitted by: G2P

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.0).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.114 is higher than 0.05.
