Genes affected
MBOAT1 (HGNC:21579): (membrane bound O-acyltransferase domain containing 1) This gene belongs to the membrane-bound O-acetyltransferase superfamily. The encoded transmembrane protein is an enzyme that transfers organic compounds, preferably from oleoyl-CoA, to hydroxyl groups of protein targets in membranes. A translocation disrupting this gene may be associated with brachydactyly syndactyly syndrome. Alternately spliced transcript variants have been described for this gene.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 23, 2023 | The c.731A>G (p.K244R) alteration is located in exon 8 (coding exon 8) of the MBOAT1 gene. This alteration results from a A to G substitution at nucleotide position 731, causing the lysine (K) at amino acid position 244 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
