Glycogen Storage Disease
- Lactate Dehydrogenase A DeficiencyAutosomal recessive
Caused by variants in LDHA, which cause exercise-related muscle breakdown and sometimes skin rashes.
- 3 GenCC submitters rate it definitive or strong
What knowing changes
Knowing helps avoid triggers of muscle breakdown and supports fast treatment.
Inheritance
- Autosomal recessive
- It takes a changed copy from each parent. With one, you are a carrier and usually unaffected; when both parents are carriers, each child has a one-in-four chance of inheriting two.
How LDHA is laid out

- Direction of transcription
- Known disease-causing sites
- Stretches short reads find hard
Exons of the gene's MANE Select transcript (release v1.5), from NCBI and EMBL-EBI, on the GRCh38 reference genome.
Chromosome bands from UCSC's GRCh38 ideogram (2022-10-29).
Nearby genes from Ensembl release 116, on GRCh38.
Exons make up 2.2 kb of the gene's 13.9 kb; 999 of those bases code for the protein.
How a genome test reads LDHA
12
positions in LDHA where ClinVar classes a change as pathogenic or likely pathogenic
None of them falls in a region short reads find hard.
A whole genome covers all 13.9 kb of LDHA, introns included, not only the 2.2 kb of exons.
