Genes affected

ABHD14B (HGNC:28235): (abhydrolase domain containing 14B) Enables hydrolase activity. Involved in positive regulation of transcription by RNA polymerase II. Located in cytosol; nucleolus; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ABHD14B links:

ABHD14A (HGNC:24538): (abhydrolase domain containing 14A) Predicted to enable hydrolase activity. Predicted to be integral component of membrane. Predicted to be active in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ABHD14A links:

PCBP4 (HGNC:8652): (poly(rC) binding protein 4) This gene encodes a member of the KH-domain protein subfamily. Proteins of this subfamily, also referred to as alpha-CPs, bind to RNA with a specificity for C-rich pyrimidine regions. Alpha-CPs play important roles in post-transcriptional activities and have different cellular distributions. This gene is induced by the p53 tumor suppressor, and the encoded protein can suppress cell proliferation by inducing apoptosis and cell cycle arrest in G(2)-M. This gene's protein is found in the cytoplasm, yet it lacks the nuclear localization signals found in other subfamily members. Multiple alternatively spliced transcript variants have been described, but the full-length nature for only some has been determined. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.65G>A (p.R22Q) alteration is located in exon 2 (coding exon 1) of the ABHD14B gene. This alteration results from a G to A substitution at nucleotide position 65, causing the arginine (R) at amino acid position 22 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
