Variant summary
Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PM1PM2PM5PP3_StrongPP5_Moderate
The NM_000202.8(IDS):c.1433A>G(p.Asp478Gly) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D478Y) has been classified as Likely pathogenic.

Genes affected
IDS (HGNC:5389): (iduronate 2-sulfatase) This gene encodes a member of the sulfatase family of proteins. The encoded preproprotein is proteolytically processed to generate two polypeptide chains. This enzyme is involved in the lysosomal degradation of heparan sulfate and dermatan sulfate. Mutations in this gene are associated with the X-linked lysosomal storage disease mucopolysaccharidosis type II, also known as Hunter syndrome. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed. [provided by RefSeq, Jan 2016]

ACMG classification
Classification made for transcript
Verdict is Pathogenic. Variant got 12 ACMG points.
PM1
?
In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 5 uncertain in NM_000202.8
PM2
?
Very rare variant in population databases, with high coverage;
PM5
?
Other missense variant is known to change same aminoacid residue: Variant chrnull-null-null-null is described in UniProt as null.
PP3
?
MetaRNN computational evidence supports a deleterious effect, 0.967
PP5
?
Variant X-149482966-T-C is Pathogenic according to our data. Variant chrX-149482966-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 221204.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chrX-149482966-T-C is described in Lovd as [Pathogenic].
