|
| A congenital disorder characterized by nonprogressive cerebellar ataxia, associated with a moderate to profound intellectual disability and delayed ambulation. Gait can be either bipedal or quadrupedal. Additional features include hypotonia, lack of coordination, delayed motor development, seizures, dysarthria, strabismus, short stature, and pes planus. Etiological subtypes have been reported and include type 1 (CAMRQ1), 2 (CAMRQ2), 3 (CAMRQ3) and 4 (CAMRQ4) which are attributed to mutations in VLDLR (9p24), CA8 (8q12.1), WDR81 (17p13.3) and ATP8A2 (13q12) genes, respectively. Transmission is autosomal recessive. |
