Genes affected

CHST14 (HGNC:24464): (carbohydrate sulfotransferase 14) This gene encodes a member of the HNK-1 family of sulfotransferases. The encoded protein transfers sulfate to the C-4 hydroxyl of N-acetylgalactosamine residues in dermatan sulfate. Mutations in this gene have been associated with adducted thumb-clubfoot syndrome.[provided by RefSeq, Mar 2010]

Computational evidence support a benign effect (BayesDel_noAF=-0.73).

BP6

Variant 15-40472020-T-C is Benign according to our data. Variant chr15-40472020-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 262313.

BP7

Synonymous conserved (PhyloP=-1.13 with no splicing effect.

BS1

Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000998 (152/152284) while in subpopulation AMR AF = 0.000849 (13/15310). AF 95% confidence interval is 0.000502. There are 0 homozygotes in GnomAd4. There are 66 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 10 AR gene
