This alteration results from a C to G substitution at nucleotide position 1406, causing the proline (P) at amino acid position 469 to be replaced by an arginine (R). Based on data from the Genome Aggregation Database (gnomAD), the IDS c.1406C>G alteration was not observed, with coverage at this position. This alteration was reported in a patient with MPS II and low iduronate-2-sulfatase enzyme activity in plasma (Pollard, 2013). In addition, two other alterations affecting the same amino acid, p.P469H and p.P469L, were reported in patients with MPS II (Jonsson, 1995; Kosuga, 2016). This amino acid position is highly conserved in available vertebrate species. The p.P469R alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, this alteration is classified as likely pathogenic. (less)

Comment:

The c.1406C>G (p.P469R) alteration is located in exon 9 (coding exon 9) of the IDS gene. This alteration results from a C to G substitution at nucleotide position 1406, causing the proline (P) at amino acid position 469 to be replaced by an arginine (R). Based on data from the Genome Aggregation Database (gnomAD), the IDS c.1406C>G alteration was not observed, with coverage at this position. This alteration was reported in a patient with MPS II and low iduronate-2-sulfatase enzyme activity in plasma (Pollard, 2013). In addition, two other alterations affecting the same amino acid, p.P469H and p.P469L, were reported in patients with MPS II (Jonsson, 1995; Kosuga, 2016). This amino acid position is highly conserved in available vertebrate species. The p.P469R alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, this alteration is classified as likely pathogenic.

Comment:

Absent from controls (or at low frequency) in gnomAD database (PM2_Moderate), Missense variant in a gene with a low rate of benign missense variation (PP2_Supporting), Multiple lines of computational evidence support a deleterious effect (PP3_Supporting), Patient’s phenotype or family history highly specific for the disease (PP4_Strong)
