Genes affected

SLC26A2 (HGNC:10994): (solute carrier family 26 member 2) The diastrophic dysplasia sulfate transporter is a transmembrane glycoprotein implicated in the pathogenesis of several human chondrodysplasias. It apparently is critical in cartilage for sulfation of proteoglycans and matrix organization. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.74).
• BP6: Variant 5-149960774-C-T is Benign according to our data. Variant chr5-149960774-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 1191571.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00399 (608/152384) while in subpopulation AFR AF = 0.014 (581/41598). AF 95% confidence interval is 0.013. There are 9 homozygotes in GnomAd4. There are 276 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 9 AR gene
