Genes affected
ABHD1 (HGNC:17553): (abhydrolase domain containing 1) This gene is a member of the AB hydrolase superfamily and encodes a protein with an alpha/beta hydrolase fold. This domain is common to a number of hydrolytic enzymes of widely differing phylogenetic origins and catalytic functions. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 29, 2024The c.853C>T (p.R285C) alteration is located in exon 8 (coding exon 8) of the ABHD1 gene. This alteration results from a C to T substitution at nucleotide position 853, causing the arginine (R) at amino acid position 285 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
