Genes affected

CHST3 (HGNC:1971): (carbohydrate sulfotransferase 3) This gene encodes an enzyme which catalyzes the sulfation of chondroitin, a proteoglycan found in the extracellular matrix and most cells which is involved in cell migration and differentiation. Mutations in this gene are associated with spondylepiphyseal dysplasia and humerospinal dysostosis. [provided by RefSeq, Mar 2009]

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.949
• PP5: Variant 10-72007512-C-T is Pathogenic according to our data. Variant chr10-72007512-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 6050.Status of the report is no_assertion_criteria_provided, 0 stars.
