Adult onset hereditary spastic paraplegia v1.95 GJA1 Ivone Leong Tag Q3_21_rating was removed from gene: GJA1.
Adult onset hereditary spastic paraplegia v1.95 GJA1 Sarah Leigh commented on gene: GJA1
Adult onset hereditary spastic paraplegia v1.94 GJA1 Ivone Leong Source Expert Review Green was added to GJA1.
Rating Changed from Amber List (moderate evidence) to Green List (high evidence)
Adult onset hereditary spastic paraplegia v1.72 GJA1 Arina Puzriakova changed review comment from: Progressive neurological symptoms are occasionally seen in ODDD due to degeneration of the white matter tracts and can include spastic paraplegia. Gait disturbances due to spasticity can be a presenting feature for which patients initially seek medical attention. Typically signs of spasticity arise in adulthood (PMID: 18660473; 22214631; 29927410; 31023660; 33190326; 33612672); however, several adolescent onset cases (PMID: 18660473; 31023660) have also been described and I could only find a single childhood-onset case with spasticity arising at age 8 (PMID: 29927410).

Overall there is enough evidence to rate as Green on both the adult and childhood-onset HSP panels to ensure identification of all cases. >10 unrelated families reported in literature.; to: Progressive neurological symptoms are occasionally seen in ODDD due to degeneration of the white matter tracts and can include spastic paraplegia.

Overall there is enough evidence to rate as Green on the adult-onset HSP panel (>10 unrelated families reported in literature). I will seek further clinical opinion with regard to inclusion on the childhood-onset panel given the implications of carrier status being found incidentally for this primarily adult-onset condition.
