RCV001249024 | SCV001422946 | likely pathogenic | Mucopolysaccharidosis type 1 | 2020-01-13 | criteria provided, single submitter | curation | The c.299+1G>T variant in IDUA has not been previously reported in individuals with mucopolysaccharidosis (MPS) but has been identified in 0.004% (1/27550) of Latino chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs398123259). Although this variant has been seen in the general population, its frequency is low enough to be consistent with a recessive carrier frequency. This variant has also been reported in ClinVar (VariationID: 92639) as pathogenic by EGL Genetic Diagnostics and as likely pathogenic by Counsyl. This variant occurs in the invariant region (+/- 1/2) of the splice consensus sequence and is predicted to cause altered splicing leading to an abnormal or absent protein. Loss of function of the IDUA gene is an established disease mechanism in autosomal recessive MPS. In summary, although additional studies are required to fully establish its clinical significance, this variant is likely pathogenic. ACMG/AMP Criteria applied: PVS1_strong, PM2 (Richards 2015). |
