ref(2)P is the Drosophila homolog of p62/SQSTM1, and this modifier is of particular interest because SQSTM1 mutations that cause loss of selective autophagy cause ALS/FTD (Cirulli et al., 2015; Goode et al., 2016; Le Ber et al., 2013), and p62 aggregates are pathological features of both familial and sporadic ALS (Al-Sarraj et al., 2011; Cooper-Knock et al., 2012). The gene discussed is SQSTM1; the disease is frontotemporal dementia.
