ORPHA:2364Disease
Also called GSD due to lactate dehydrogenase deficiency · Glycogenosis due to lactate dehydrogenase deficiency · LDH deficiency
What it is
A rare genetic glycogen storage disease characterized by either lactate dehydrogenase (LDH) M- or H-subunit deficiency. Main features of LDH M-subunit deficiency are exertional fatigue and muscle pain potentially accompanied by myoglobinuria. Some patients may develop pustular psoriasis-like skin lesions. Complications of pregnancy, such as frequent abdominal pains and increased uterine tone with a risk of dystocia have also been described. LDH H-subunit deficiency manifests with low serum LDH activity of unclear clinical relevance.

Orphanet records these for the broader condition rather than for this specific form. They are a starting point, not a figure for this subtype — subtypes often differ, and some are defined by being rarer than the condition they sit under.

6These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.
Genes reported in subtypes
Orphanet records these genes on 2 more specific entries under this disorder, not on this entry itself:
A well-studied disease is usually split into subtypes, and the gene is curated on whichever one the evidence belongs to. Open a subtype to see which gene goes with it.
ICD-10 codes
ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.

Reached through the ICD-10 categories this disease is filed under, so these describe the broader group rather than this disease specifically.
