Genes linked to BLOOD GROUP, WALDNER
SLC4A1: Band 3 anion transport protein
In red blood cells it exchanges chloride and bicarbonate to support carbon-dioxide transport, while in renal intercalated cells it is required for acid-base regulation. Pathogenic variants can cause hereditary spherocytosis or distal renal tubular acidosis depending on the affected function.
1 disease-causing and 71 uncertain variants in SLC4A1 are linked to BLOOD GROUP, WALDNER.
Known disease-causing variants in BLOOD GROUP, WALDNER
| Variant | Position | Protein part | Clinical label |
|---|---|---|---|
| SLC4A1 A858D | 858 | Discontinuously helical | Disease-causing (★★) |
Same protein, different disease
- Hereditary spherocytosis is also caused by SLC4A1 variants; they fall mostly in different places as the BLOOD GROUP, WALDNER variants (13 disease-causing).
- Autosomal dominant distal renal tubular acidosis is also caused by SLC4A1 variants; they fall mostly in different places as the BLOOD GROUP, WALDNER variants (11 disease-causing).
- Cryohydrocytosis is also caused by SLC4A1 variants; they fall mostly in different places as the BLOOD GROUP, WALDNER variants (9 disease-causing).

About this data
Variant–disease links come from ClinVar, Open Targets and UniProt, pooled from the latest public CATVariant analysis of each human protein. Evidence scores use the ACMG/AMP Bayesian points scale with computable criteria only (position among known disease variants, rarity in gnomAD, calibrated predictors, deep mutational scanning); there is no family or patient data, so they prioritise variants for expert review and never classify them.
