Genes affected
GNS (HGNC:4422): (glucosamine (N-acetyl)-6-sulfatase) The product of this gene is a lysosomal enzyme found in all cells. It is involved in the catabolism of heparin, heparan sulphate, and keratan sulphate. Deficiency of this enzyme results in the accumulation of undegraded substrate and the lysosomal storage disorder mucopolysaccharidosis type IIID (Sanfilippo D syndrome). Mucopolysaccharidosis type IIID is the least common of the four subtypes of Sanfilippo syndrome. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.006198585).
BP6
Variant 12-64716802-C-T is Benign according to our data. Variant chr12-64716802-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 258550.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0087 (1324/152220) while in subpopulation AFR AF = 0.0302 (1254/41528). AF 95% confidence interval is 0.0288. There are 18 homozygotes in GnomAd4. There are 619 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 18 AR gene
