Genes affected

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:

ABHD14A-ACY1 (HGNC:38856): (ABHD14A-ACY1 readthrough) This locus represents naturally occurring read-through transcription between the neighboring abhydrolase domain containing 14A (ABHD14A) and aminoacylase 1 (ACY1) genes on chromosome 3. The read-through transcript encodes a protein that shares sequence identity with the downstream gene product but its N-terminal region is distinct due to the use of an alternate start codon relative to the upstream gene. [provided by RefSeq, Oct 2015]

ABHD14A-ACY1 links:

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]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.200A>G (p.N67S) alteration is located in exon 2 (coding exon 2) of the ABHD14A gene. This alteration results from a A to G substitution at nucleotide position 200, causing the asparagine (N) at amino acid position 67 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
