Added comment: Homozygosity mapping on one large consanguineous Bedouin kindred showed three affected children (out of the ten) to be homozygous for NM_002802.3:c.983T>C; p.(Ile328Thr).

Drosophila rescue experiments were carried out. Transgenic studies using drosophila with the silenced ortholog Rpt2 gene were rescued by the human wild-type PSMC1.

Three of the ten offspring of healthy consanguineous parents of Bedouin Israeli ancestry were affected with a similar phenotype of failure to thrive, developmental delay and severe intellectual disability, spastic tetraplegia with central hypotonia, chorea, as well as hearing loss. None of the three achieved verbal communication or ambulation (sitting / standing) at any age. They had mild dysmorphism of borderline dolichocephaly and microcephaly, prominent bushy eyebrows, flat midface, long nasal bridge and micrognathia. All three had micropenis with undescended testes. One of the affected (as a toddler) underwent thorough endocrinological analysis: testosterone and gonadotropin levels were low.
