Genes affected

CTSD (HGNC:2529): (cathepsin D) This gene encodes a member of the A1 family of peptidases. The encoded preproprotein is proteolytically processed to generate multiple protein products. These products include the cathepsin D light and heavy chains, which heterodimerize to form the mature enzyme. This enzyme exhibits pepsin-like activity and plays a role in protein turnover and in the proteolytic activation of hormones and growth factors. Mutations in this gene play a causal role in neuronal ceroid lipofuscinosis-10 and may be involved in the pathogenesis of several other diseases, including breast cancer and possibly Alzheimer's disease.

The c.592A>G (p.I198V) alteration is located in exon 5 (coding exon 5) of the CTSD gene. This alteration results from a A to G substitution at nucleotide position 592, causing the isoleucine (I) at amino acid position 198 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 198 of the CTSD protein (p.Ile198Val). This variant is present in population databases (rs556334193, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with CTSD-related conditions. ClinVar contains an entry for this variant (Variation ID: 527749). 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 not expected to disrupt CTSD protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
