General annotation (Comments)
| Tissue specificity | Highly expressed in the most primitive normal hematopoietic cells. Expressed in brain, particularly in neurons that give rise to the crossing axons of the corticospinal tract and superior cerebellar peduncles. Ref.6 Ref.7 |
| Induction | Down-regulated during early differentiation of normal hematopoietic cells. Up-regulated in leukemic cells at all stages of differentiation from patients with chronic myeloid leukemia. Ref.6 |
| Involvement in disease | Defects in AHI1 are the cause of Joubert syndrome type 3 (JBTS3) [MIM:608629]. JBTS is an autosomal recessive disorder presenting with cerebellar ataxia, oculomotor apraxia, hypotonia, neonatal breathing abnormalities and psychomotor delay. Neuroradiologically, it is characterized by cerebellar vermian hypoplasia/aplasia, thickened and reoriented superior cerebellar peduncles, and an abnormally large interpeduncular fossa, giving the appearance of a molar tooth on transaxial slices (molar tooth sign). Additional variable features include retinal dystrophy and renal disease. JBTS3 shows minimal extra central nervous system involvement and appears not to be associated with renal dysfunction. Ref.7 Ref.10 Ref.11 |
| Sequence similarities | Contains 1 SH3 domain. Contains 7 WD repeats. |
| Sequence caution | The sequence AAH29417.1 differs from that shown. Reason: Miscellaneous discrepancy. Contaminating sequence. Potential poly-A sequence. The sequence AAH65712.1 differs from that shown. Reason: Miscellaneous discrepancy. Contaminating sequence. Potential poly-A sequence. The sequence CAI20201.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI20387.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI22523.1 differs from that shown. Reason: Erroneous gene model prediction. |
