UniProtKB/Swiss-Prot : 73 Spinocerebellar ataxia 42, early-onset, severe, with neurodevelopmental deficits: A form of spinocerebellar ataxia, a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA42ND is an early- onset, severe form associated with motor and cognitive impairment, cerebellar atrophy as well as variable features such as facial dysmorphisms, digital anomalies, microcephaly and epilepsy. SCA42ND inheritance is autosomal dominant.

MalaCards based summary : Spinocerebellar Ataxia 42, Early-Onset, Severe, with Neurodevelopmental Deficits, also known as sca42nd, is related to ataxia and polyneuropathy, adult-onset and spinocerebellar ataxia 42. An important gene associated with Spinocerebellar Ataxia 42, Early-Onset, Severe, with Neurodevelopmental Deficits is CACNA1G (Calcium Voltage-Gated Channel Subunit Alpha1 G). Affiliated tissues include eye, cerebellum and spinal cord, and related phenotypes are microcephaly and intellectual disability
