Description

A homozygous variant in exon 5 of the IDUA gene that results in the amino acid substitution of cystein for phenylalanine at codon 177 was detected. The observed variant c.530T>G (p.Phe177Cys) has not been reported in gnomAD databases. The in silico prediction of the variant are possibly damaging by SIFT, DANN and MutationTaster2. The reference codon is conserved across species. In summary, the variant meets our criteria to be classified as pathogenic.
