Hereditary Sideroblastic Anaemias
- Inherited Sideroblastic Anaemia
A group of conditions caused by changes in genes such as ALAS2 and ABCB7 (X-linked), SLC25A38, GLRX5, PUS1, YARS2 and TRNT1 (recessive) and HSPA9 (dominant); some forms also affect the muscles, nervous system or immune system.
- 4 GenCC submitters rate it definitive or strong
What knowing changes
The X-linked ALAS2 form often responds to vitamin B6 (pyridoxine), and a diagnosis guides iron-overload monitoring and distinguishes these conditions from acquired myelodysplastic syndrome.
How ABCB7 is laid out
- Coding sequence
- Untranslated region
- Intron
- 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 4.6 kb of the gene's 105.2 kb; 2,259 of those bases code for the protein.
How a genome test reads ABCB7

positions in ABCB7 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 105.2 kb of ABCB7, introns included, not only the 4.6 kb of exons.
