Department of Medical Genetics, University of Pecs	RCV000845572	SCV000886727	likely pathogenic	Autosomal dominant limb-girdle muscular dystrophy type 1D (DNAJB6)	2018-12-05	criteria provided, single submitter	clinical testing	The patient's father is also affected with the same heterozygous mutation in the reported position, and they both have a milder phenotype of LGMD1D. LGMD1D cases were reported with different mutations in the same position resulting in more severe phenotype (Ruggieri et al. 2016, Palmio et al. 2015).
Labcorp Genetics (formerly Invitae), Labcorp	RCV000845572	SCV002288744	likely pathogenic	Autosomal dominant limb-girdle muscular dystrophy type 1D (DNAJB6)	2022-08-04	criteria provided, single submitter	clinical testing	This sequence change replaces phenylalanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 91 of the DNAJB6 protein (p.Phe91Val). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of DNAJB6-related conditions (PMID: 30564623, 31034989). ClinVar contains an entry for this variant (Variation ID: 498056). 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 DNAJB6 protein function. This variant disrupts the p.Phe91 amino acid residue in DNAJB6. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 26205529, 26338452, 26371419). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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.
