Genes affected
ABHD16A (HGNC:13921): (abhydrolase domain containing 16A, phospholipase) A cluster of genes, BAT1-BAT5, has been localized in the vicinity of the genes for tumor necrosis factor alpha and tumor necrosis factor beta. These genes are all within the human major histocompatibility complex class III region. The protein encoded by this gene is thought to be involved in some aspects of immunity. Alternatively spliced transcript variants have been described. [provided by RefSeq, Apr 2010]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 26, 2024The c.1622C>A (p.A541D) alteration is located in exon 20 (coding exon 20) of the ABHD16A gene. This alteration results from a C to A substitution at nucleotide position 1622, causing the alanine (A) at amino acid position 541 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
