Genes affected
SOST (HGNC:13771): (sclerostin) Sclerostin is a secreted glycoprotein with a C-terminal cysteine knot-like (CTCK) domain and sequence similarity to the DAN (differential screening-selected gene aberrative in neuroblastoma) family of bone morphogenetic protein (BMP) antagonists. Loss-of-function mutations in this gene are associated with an autosomal-recessive disorder, sclerosteosis, which causes progressive bone overgrowth. A deletion downstream of this gene, which causes reduced sclerostin expression, is associated with a milder form of the disorder called van Buchem disease. [provided by RefSeq, Jul 2008]

This sequence change creates a premature translational stop signal (p.Gln24*) in the SOST gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SOST are known to be pathogenic (PMID: 11179006, 20301406). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with sclerosteosis (PMID: 11179006). ClinVar contains an entry for this variant (Variation ID: 4783). For these reasons, this variant has been classified as Pathogenic. -
