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

Our verdict: Likely_benign. The variant received -5 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.81).
• BS1: Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000219 (21/958626) while in subpopulation SAS AF = 0.000214 (16/74834). AF 95% confidence interval is 0.000133. There are 0 homozygotes in GnomAdExome4. There are 17 alleles in the male GnomAdExome4 subpopulation. Median coverage is 13. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
