Presentation
Characterised as a recessive disorder, symptomatic presentation requires the inheritance of aldolase A mutations from both parents. [en.wikipedia.org]
[…] aldolase A deficiency Glycogenosis type 12 Glycogenosis type XII Prevalence: Unknown Inheritance: Autosomal recessive Age of onset: Neonatal ICD-10: E74.0 OMIM: 611881 UMLS: C0272066 MeSH: - GARD: 600 MedDRA: - The documents contained in this web site are presented [orpha.net]
The sole aldolase present in red blood cells and skeletal muscle is the A isozyme. We report here the case of a girl of Sicilian descent with aldolase A deficiency. [ncbi.nlm.nih.gov]

Anemia
Abstract Two cases of red cell aldolase deficiency associated with congenital nonspherocytic hemolytic anemia are reported. The proband is a fourteen‐month‐old Japanese boy. [doi.org]
A family with episodic rhabdomyolysis (triggerd by fever) without hemolytic anemia has recently been reported. [orpha.net]
Fructose-1,6-bisphosphate aldolase A (fructose-bisphosphate aldolase; EC 4.1.2.13) deficiency is an autosomal recessive disorder associated with hereditary hemolytic anemia. [ncbi.nlm.nih.gov]

Fever
A family with episodic rhabdomyolysis (triggerd by fever) without hemolytic anemia has recently been reported. [orpha.net]
To the Editor: In their Brief Report (April 25 issue), 1 Kreuder et al. report the aggravation of rhabdomyolysis by fever and suggest thermolability of the mutant enzyme as a possible cause for the increase. [doi.org]
Deterioration with fever is likewise congruent. [en.wikipedia.org]

Weakness
This is often recognized initially through signs of muscle weakness and exercise intolerance, suggesting rapid muscular fatigue and damage, likely directly related to ATP depletion. [en.wikipedia.org]
Clinical manifestations included transfusion-dependent anemia until splenectomy at age 3 and increasing muscle weakness, with death at age 4 associated with rhabdomyolysis and hyperkalemia. [ncbi.nlm.nih.gov]

Neurologic examination at age 2, prompted by a seizure, revealed Gowers sign without other evidence of weakness. Cognitive function was normal. [doi.org]

Recurrent Infection
This was correlated with recurrent infection in the Sicilian case.Focal disruption of vital energy metabolism has thus far prevented complete investigation of non-catalytic perturbation. [en.wikipedia.org]
Aldolase A is reported to be the predominant or sole aldolase in leukocytes. 14 It is possible that the recurrent infections in the patient, in particular disseminated Pseudomonas, resulted from defective bacterial killing. [doi.org]

Suggestibility
When compared with normal human aldolase A, the patient's enzyme from erythrocytes and from cultured lymphoblastoid cells was found to be highly thermolabile, suggesting that this mutation causes a functional defect of the enzyme. [ncbi.nlm.nih.gov]
A complex pattern for this metabolite is suggested with discrepancy in findings. [en.wikipedia.org]

Addition of glycerol or some other polyalcohols during thermal treatment protected this altered enzyme (but not the normal enzyme) against denaturation and activity decrease. [ncbi.nlm.nih.gov]

Etiology
On the other hand, the late-onset variant of GSD IV (adult polyglucosan body disease APBD) is one of several polyglucosan disorders (including Lafora disease) due to different etiologies. [ncbi.nlm.nih.gov]

Prevention
Early developmental reliance and constitutive function prevents severe mutation in successful embryos. Infrequent documentation thus prevents clear generalisation of symptoms and causes. However five cases have been well described. [en.wikipedia.org]
