IDENTIFICATION OF SPECIES OF ORIGIN |
Species of Origin Confirmed by Nucleoside Phosphorylase Isoenzyme Electrophoresis |
|
methylcrotonyl-CoA carboxylase |
According to the submitter, biochemical test results for this subject showed decreased enzyme activity. EC Number: 6.4.1.4 |
|
Remarks |
Clinically affected; product of a twin pregnancy; holocarboxylase synthetase deficient; acidosis; "cat urine" odor; shock; responded well to biotin treatment; mother was given supplemental biotin in the last trimester of pregnancy due to history of two previously affected infants; deficient propionyl CoA carboxylase, pyruvate carboxylase, and B-methylcrotonyl CoA carboxylase |
