Genes affected

ANKHD1 (HGNC:24714): (ankyrin repeat and KH domain containing 1) This gene encodes a protein with multiple ankyrin repeat domains and a single KH-domain. The protein is thought to function as a scaffolding protein, and it may be involved in the regulation of caspases and thereby play an antiapoptotic role in cell survival. Alternative splicing results in multiple transcript variants, one of which generates a fusion transcript (MASK-BP3) with the downstream eIF4E-binding protein 3 (EIF4EBP3) gene, resulting in a protein comprised of the ANKHD1 sequence for the majority of the protein and a different C-terminus due to an alternate reading frame for the EIF4EBP3 segments.

The c.518G>A (p.R173Q) alteration is located in exon 3 (coding exon 3) of the ANKHD1-EIF4EBP3 gene. This alteration results from a G to A substitution at nucleotide position 518, causing the arginine (R) at amino acid position 173 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
