The molecular basis of a significant number of cases of isolated
growth hormone deficiency remains unknown. We describe three
sisters affected with severe isolated growth hormone deficiency and
pituitary hypoplasia caused by biallelic mutations in the RNPC3 gene,
which codes for a minor spliceosome protein required for U11/U12
small nuclear ribonucleoprotein (snRNP) formation and splicing
of U12-type introns. We found anomalies in U11/U12 di-snRNP
formation and in splicing of multiple U12-type introns in patient
cells. Defective transcripts include preprohormone convertases
SPCS2 and SPCS3 and actin-related ARPC5L genes, which are
candidates for the somatotroph-restricted dysfunction. The
reported novel mechanism for familial growth hormone deficiency
demonstrates that general mRNA processing defects of the minor
spliceosome can lead to very narrow tissue-specific consequences
