Remarks

Clinically affected; diagnosed by newborn screening; hospitalized for decreased feeding; low muscle tone, hypothermia, severe hyperammonemia and metabolic acidosis; markedly elevated propionic acid metabolites by urine organic acid analysis; no family history; on levocarnitine; donor subject is homozygous for a 14 bp deletion and a 12 bp insertion at nucleotide 1218 in exon 12 of the PCCB gene [c.1218_1231delinsTAGAGCACAGGA (c.1218del14ins12)] resulting in a frameshift and stop codon at Gly406 (Gly406fs)

Species of Origin confirmed by LINE assay

Gene

PCCB

Chromosomal Location

3q21-q22

Allelic Variant 1

232050.0003; PROPIONIC ACIDEMIA

Identified Mutation

12-BP INS, 14-BP DEL, NT1218; Rodriguez-Pombo et al. (1998) found that the most frequent mutation causing PCCB deficiency (606054) in Spain and Latin America was an insertion/deletion of 12 bp and 14 bp, respectively, following nucleotide 1218. This mutation accounted for 31% of the alleles from Spanish patients and 47% of the alleles from Latin American patients. The ins/del caused a frameshift and a premature stop codon in the coding sequence.
