Genes affected

PALM2AKAP2 (HGNC:33529): (PALM2 and AKAP2 fusion) This gene belongs to the paralemmin downstream gene (PDG) family defined in PMID:22855693. Paralemmin downstream genes may have evolved contiguously with the paralemmin genes and are associated with other paralemmin paralogs in humans and several other taxa. The gene encodes three distinct protein isoforms, the PALM2 isoform, the AKAP2 isoform and the PALM2-AKAP2 isoform. The biological significance of the PALM2-AKAP2 isoforms is yet unknown. Earlier, PALM2 and AKAP2 were annotated as separate genes and PALM2-AKAP2 was annotated as a readthrough gene. [provided by RefSeq, May 2019]

Ambry Genetics

Jan 26, 2023

The c.35A>G (p.Q12R) alteration is located in exon 1 (coding exon 1) of the PALM2-AKAP2 gene. This alteration results from a A to G substitution at nucleotide position 35, causing the glutamine (Q) at amino acid position 12 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
