Another homozygous MRPS7 mutation (c.550A>G, p.M184V), found in two patients, resulted in sensorineural deafness combined with lactic acidemia, progressive renal and hepatic failure and, at least in one of them, primary hypogonadism (Menezes et al., 2015); it was recently proposed to be reclassified as Perrault syndrome (Kline et al., 2022). The gene discussed is MRPS7; the disease is Perrault syndrome.
