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]

The c.826G>A (p.D276N) alteration is located in exon 7 (coding exon 7) of the ABHD1 gene. This alteration results from a G to A substitution at nucleotide position 826, causing the aspartic acid (D) at amino acid position 276 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
