Labcorp Genetics (formerly Invitae), Labcorp RCV001378854 SCV001576534 likely pathogenic Mucopolysaccharidosis type 6 2021-01-17 criteria provided, single submitter clinical testing In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant disrupts the p.His147 amino acid residue in ARSB. Other variant(s) that disrupt this residue have been observed in individuals with ARSB-related conditions (PMID: 26909334), which suggests that this may be a clinically significant amino acid residue. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt ARSB protein function. This variant has been observed in individual(s) with mucopolysaccharidosis type VI (Invitae). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. This variant is not present in population databases (ExAC no frequency). This sequence change replaces histidine with glutamine at codon 147 of the ARSB protein (p.His147Gln). The histidine residue is highly conserved and there is a small physicochemical difference between histidine and glutamine.
