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]

The c.5005G>A (p.E1669K) alteration is located in exon 27 (coding exon 26) of the KIAA0430 gene. This alteration results from a G to A substitution at nucleotide position 5005, causing the glutamic acid (E) at amino acid position 1669 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
