Genes affected

NDST1 (HGNC:7680): (N-deacetylase and N-sulfotransferase 1) This gene encodes a member of the heparan sulfate/heparin GlcNAc N-deacetylase/ N-sulfotransferase family. The encoded enzyme is a type II transmembrane protein that resides in the Golgi apparatus. The encoded protein catalyzes the transfer of sulfate from 3'-phosphoadenosine 5'-phosphosulfate to nitrogen of glucosamine in heparan sulfate. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2014]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PM1: In a region_of_interest Heparan sulfate N-sulfotransferase 1 (size 283) in uniprot entity NDST1_HUMAN there are 6 pathogenic changes around while only 1 benign (86%) in NM_001543.5
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, NDST1
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.854
• PP5: Variant 5-150542927-G-T is Pathogenic according to our data. Variant chr5-150542927-G-T is described in ClinVar as [Pathogenic]. Clinvar id is 161410.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr5-150542927-G-T is described in Lovd as [Pathogenic].
