Author(s): Radha Rama Devi* and Nalinikanth Panigrahi
Malonyl-CoA decarboxylase deficiency causing isolated malonic aciduria is a rare inborn error of metabolism
with heterogeneous phenotypic manifestations. The disease can be diagnosed in new-born screening. Early
treatment prevents development of cardiomyopathy and intellectual disability. Tandem Mass Spectrometer (TMS) and urine Gas Chromatography Mass Spectrometry (GC-MS) and whole exome sequencing confirms the diagnosis.
Results: Two patients from unrelated families were diagnosed with elevated C3DC acyl carnitine and increases
excretion of malonic acid in the urine. The concentration of malonic acid in the urine was very high in case 1 as the
test was done during acute crisis (423-fold elevation). Case 2 had 11-fold elevation (not in decompensation). No
methyl malonic acid was detected in both the cases. Both the patients harbored novel mutat.. View More»
