Genes affected
CTSH (HGNC:2535): (cathepsin H) The protein encoded by this gene is a lysosomal cysteine proteinase important in the overall degradation of lysosomal proteins. It is composed of a dimer of disulfide-linked heavy and light chains, both produced from a single protein precursor. The encoded protein, which belongs to the peptidase C1 protein family, can act both as an aminopeptidase and as an endopeptidase. Increased expression of this gene has been correlated with malignant progression of prostate tumors. Alternate splicing of this gene results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jan 2016]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.06746032 fraction of the gene. No cryptic splice site detected. Exon removal is inframe change.
PP3
Multiple lines of computational evidence support a deleterious effect 5: Cadd, dbscSNV1_ADA, dbscSNV1_RF, max_spliceai, Eigen [when BayesDel_addAF, MutationTaster was below the threshold]
BP6
Variant 15-78927712-C-T is Benign according to our data. Variant chr15-78927712-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 758792.Status of the report is criteria_provided_single_submitter, 1 stars.
BS2
High Homozygotes in GnomAdExome4 at 2 AR gene
