Variant summary

Our verdict is Pathogenic. The variant received 20 ACMG points: 20P and 0B. PVS1PS3PP5_Very_Strong

The NM_000199.5(SGSH):c.697C>T(p.Arg233*) variant causes a stop gained change. The variant allele was found at a frequency of 0.0000305 in 1,608,344 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV000695959: This change is predicted to cause loss of normal protein function through protein truncation or nonsense-mediated mRNA decay, which was proven by RNA and protein expression studies (Muschol, 2004).". Synonymous variant affecting the same amino acid position (i.e. R233R) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Genes affected

SGSH (HGNC:10818): (N-sulfoglucosamine sulfohydrolase) This gene encodes the enzyme sulfamidase; one of several enzymes involved in the lysosomal degradation of heparan sulfate. Mutations in this gene are associated with the lysosomal storage disease mucopolysaccaridosis IIIA, also known as Sanfilippo syndrome A, which results from impaired degradation of heparan sulfate. Transcripts of varying sizes have been reported but their biological validity has not been determined. [provided by RefSeq, Jun 2017]

SGSH links:

CARD14 (HGNC:16446): (caspase recruitment domain family member 14) This gene encodes a caspase recruitment domain-containing protein that is a member of the membrane-associated guanylate kinase (MAGUK) family of proteins. Members of this protein family are scaffold proteins that are involved in a diverse array of cellular processes including cellular adhesion, signal transduction and cell polarity control. This protein has been shown to specifically interact with BCL10, a protein known to function as a positive regulator of cell apoptosis and NF-kappaB activation. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Apr 2012]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 20 ACMG points.

PVS1

Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.

PS3

PS3 evidence extracted from ClinVar submissions: SCV000695959: This change is predicted to cause loss of normal protein function through protein truncation or nonsense-mediated mRNA decay, which was proven by RNA and protein expression studies (Muschol, 2004).

PP5

Variant 17-80213852-G-A is Pathogenic according to our data. Variant chr17-80213852-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 370732.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
