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 GeneticsMay 09, 2024The c.197C>T (p.T66M) alteration is located in exon 2 (coding exon 2) of the ABHD1 gene. This alteration results from a C to T substitution at nucleotide position 197, causing the threonine (T) at amino acid position 66 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
