Area Of Science
- Pediatric Hematology
- Rare Genetic Disorders
- Immunology
Background
- Infants can present with symptoms overlapping between metabolic and immune disorders.
- Glycogen storage disease type I (GSD I) and haemophagocytic lymphohistiocytosis (HLH) share clinical features like hepatomegaly.
- Accurate diagnosis is crucial for appropriate management of life-threatening conditions in infants.
Purpose Of The Study
- To highlight a case of misdiagnosis in an infant with overlapping clinical presentations.
- To emphasize the importance of genetic testing in differentiating metabolic from immune disorders.
- To present a case of X-linked lymphoproliferative syndrome presenting as HLH.
Main Methods
- Clinical presentation analysis of an infant with hepatomegaly and metabolic derangements.
- Differential diagnosis including Glycogen Storage Disease Type I.
- Genetic testing to identify pathogenic mutations.
- Diagnostic confirmation of haemophagocytic lymphohistiocytosis.
Main Results
- Initial symptoms mimicked Glycogen Storage Disease Type I.
- Genetic analysis revealed a mutation linked to X-linked lymphoproliferative syndrome.
- The patient was diagnosed with haemophagocytic lymphohistiocytosis, not GSD I.
- Treatment with immunosuppression was initiated.
Conclusions
- Clinical suspicion and comprehensive genetic evaluation are vital for diagnosing rare pediatric conditions.
- X-linked lymphoproliferative syndrome can present atypically, mimicking metabolic disorders.
- Timely diagnosis and treatment of HLH are critical for patient outcomes.

Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
Class I comprises GLUT1 to GLUT4 and GLUT14.
Class II has GLUT5, GLUT7,...
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
Y chromosome mutations are called “Y-linked” and only affect males since they alone carry a copy of that chromosome. Mutations to the relatively small Y chromosome can impact male sexual function and secondary sex characteristics. Y-chromosome infertility is a disorder that affects...
