Prognosis The severe infantile form may lead to sudden death during infancy due, in general, to paroxysmal cardiac arrhythmias. This is particularly true for undiagnosed cases.[orpha.net]
What is the prognosis? If the enzyme is completely lost there is rapid progression of the condition leading to death in infancy. If some enzyme activity remains, little or no progression with normal strength between episodes.[mda.org.au]
In some of the more severe infantile forms, there is a very poor prognosis.[idph.state.il.us]
Coma – Muscle pain and weakness – Weak heart muscle – Irregular heart beat – Enlarged liver – Liver failure Myopathic Form – Muscle pain and weakness – Muscle tissue breakdown – Discolored urine (e.g. red/brown) – Kidney issues( e.g. kidney failure) PROGNOSIS[evolvegene.com]
Etiology Missense mutations in the CPT2 gene result in the infantile form of CPT II deficiency. Contrary to the adult myopathic form (see this term), no S113L mutations have ever been detected in the infantile form.[orpha.net]
Presence or absence of an anion gap (AG) can help to distinguish the underlying etiology. In general, with a pure or uncompensated metabolic acidosis, every 10 mEq/L fall in bicarbonate (HCO 3 ) results in an average pH fall of 0.15.[mhmedical.com]
The molecular etiologies of these syndromes have not been determined. In this investigation, we considered the hypothesis that these syndromes result from defective transport of carnitine into tissues, particularly skeletal muscle.[osti.gov]

Pathophysiologic findings The CPT system mediates the transport of long-chain fatty acids into the mitochondrial matrix.[jamanetwork.com]
[…] compared to the adult group. [17] This group concluded that both the type and location of CPT2 mutation in combination with at least one secondary genetic factor modulate the long-chain fatty acid flux and, therefore, the severity of the disease. [17] Pathophysiology[en.wikipedia.org]
The mechanism of this destabilizing effect and its pathophysiologic impact remain enigmatic. Acyl- l -carnitines with more than 10 carbons in the acyl side-chain stabilized the variant S113L against the temperature-induced inactivation.[ng.neurology.org]
The pathophysiology and molecular biology vary among different forms of SCID, however, the lack of T-cell and B-cell function is the common endpoint in all forms of SCID.[genico.ch]
