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]
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.4982C>G (p.S1661C) alteration is located in exon 26 (coding exon 25) of the KIAA0430 gene. This alteration results from a C to G substitution at nucleotide position 4982, causing the serine (S) at amino acid position 1661 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
