Abstract: The identification, isolation and cloning of gl gene which when mutated is associated with bone related diseases as well as its transcript in gene products. A method of diagnostic and detection of potential carriers of this mutated gene, bone related diseases, diagnosis, gene therapy recombinant technology and therapy using the information derived from the DNA, protein and the function of the protein is also provided.

Abstract: A 3-amino-steroid of the formula ##STR1## wherein W is selected from the group consisting of hydrogen and --OH and taken together with X is ethylidene, X is selected from the group consisting of ethyl, ##STR2## the wavy line indicates the substituent has the .alpha.- and .beta.-position, R.sub.1 is selected from the group consisting of hydrogen and --CH.sub.3, R.sub.2 is selected from the group consisting of hydrogen, alkyl of 1 to 5 carbon atoms and hydroxyalkyl of 2 to 5 carbon atoms, R.sub.3 is selected from the group consisting of hydrogen, alkyl of 1 to 5 carbon atoms, hydroxyalkyl of 2 to 5 carbon atoms, acyl of organic acid of 2 to 8 carbon atoms, alkoxycarbonyl of 2 to 8 carbon atoms, acyl of an .alpha.-amino-carboxylic acid and a peptide of 2 to 3 .alpha.-amino-carboxylic acids and their non-toxic, pharmaceutically acceptable acid addition acids with the proviso that R.sub.2 and R.sub.3 are not both hydrogen and (i) when R.sub.1 is methyl, W and R.sub.2 are hydrogen and X is ##STR3## in the case R.

Abstract: Novel 1,2,3,4-tetrahydro-[9H-pyrido-[3,4-b]-indoles of the formula ##STR1## wherein R and R.sub.1 are individually selected from the group consisting of hydrogen, halogen, hydroxy, alkoxy of 1 to 5 carbon atoms and benzyloxy with the proviso that R.sub.1 is not hydroxy when R is halogen, alkoxy or benzyloxy and their non-toxic, pharmaceutically acceptable acid addition salts having tranquillizing properties and their preparation.
