Genes affected

MARF1 (HGNC:29562): (meiosis regulator and mRNA stability factor 1) This gene encodes a putative peroxisomal protein that appears to be conserved across Euteleostomi. In humans, it may be autoantigenic. [provided by RefSeq, Jul 2010]

MARF1 links:

BMERB1 (HGNC:19213): (bMERB domain containing 1) Predicted to act upstream of or within negative regulation of cell motility involved in cerebral cortex radial glia guided migration and negative regulation of microtubule depolymerization. Predicted to be located in microtubule cytoskeleton. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
