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.

ACMG classification

Verdict is Benign. Variant got -15 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.74).
• BP6: Variant 11-1757398-G-A is Benign according to our data. Variant chr11-1757398-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 205339.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-1.01 with no splicing effect.
• BS1: Variant frequency is greater than expected in population afr. gnomad4_exome allele frequency = 0.0000342 (50/1461808) while in subpopulation AFR AF= 0.000478 (16/33480). AF 95% confidence interval is 0.000299. There are 0 homozygotes in gnomad4_exome. There are 31 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
