PSPH and Williams syndrome: Our predicted HI/OMIM-associated set includes the known HI tumour suppressor NF1, along with a cluster of four genes, RPS19, RPL1, RPS7 and RPS24, associated with Diamond-Blackfan anaemia (the latter three of which are novel HI predictions), and three connected with Williams syndrome: RFC2, STX1A and PSPH (the latter two being novel HI predictions).
