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 GeneticsOct 04, 2022The c.408G>C (p.Q136H) alteration is located in exon 3 (coding exon 3) of the ABHD1 gene. This alteration results from a G to C substitution at nucleotide position 408, causing the glutamine (Q) at amino acid position 136 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
