Function
Lysophosphatidylserine (LPS) lipase that mediates the hydrolysis of lysophosphatidylserine, a class of signaling lipids that regulates immunological and neurological processes (PubMed:25290914, PubMed:30237167, PubMed:30420694, PubMed:30720278, PubMed:30643283). Represents a major lysophosphatidylserine lipase in the brain, thereby playing a key role in the central nervous system (By similarity). Also able to hydrolyze oxidized phosphatidylserine; oxidized phosphatidylserine is produced in respo... (Source: Uniprot)

HI Evidence Comments:
Biallelic loss of function mutations in ABHD12 are associated with autosomal recessive PHARC syndrome (polyneuropathy, hearing loss, cerebellar ataxia, retinitis pigmentosa, and early-onset cataracts). Fiskerstrand et al., 2010 (PMID: 20797687) describe 19 affected individuals with homozygous mutations from 4 families. Chen et al., 2013 (PMID: 24027063) describe an individual who is a compound heterozygote for a frameshift and a 59 kilobase deletion of exon 1. Eisenberger et al., 2012 (PMID: 22938382) report a patient who was initially diagnosed with Usher syndrome, type 3 but was found to have ataxia on neurological exam after a homozygous nonsense mutation in ABHD12 was detected. Nishiguchi et al, 2014 (PMID: 24697911), in addition to patients with syndromic retinitis pigmentosa, report one family with ABHD12 mutations and non-syndromic retinitis pigmentosa, illustrating some phenotypic variability.
