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

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (MetaRNN=0.048679173).
BP6
Variant 10-72007549-C-T is Benign according to our data. Variant chr10-72007549-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 445944.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1}.
BS1
Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000275 (40/1453756) while in subpopulation AMR AF= 0.000896 (40/44654). AF 95% confidence interval is 0.000676. There are 0 homozygotes in gnomad4_exome. There are 13 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck.
