Genes affected

CLPTM1L (HGNC:24308): (CLPTM1 like) The protein encoded by this gene is a membrane protein whose overexpression in cisplatin-sensitive cells causes apoptosis. Polymorphisms in this gene have been reported to increase susceptibility to several cancers, including lung, pancreatic, and breast cancers. [provided by RefSeq, Nov 2015]

ACMG classification

Verdict is Likely_benign. Variant got -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
• BP6: Variant 5-1320609-C-T is Benign according to our data. Variant chr5-1320609-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 3035456.Status of the report is no_assertion_criteria_provided, 0 stars.
