Genes affected

GLIPR1L2 (HGNC:28592): (GLIPR1 like 2) This gene encodes a member of the cysteine-rich secretory protein, antigen 5, and pathogenesis-related 1 superfamily. Members of this family have roles in a variety of processes, including cancer and immune defense. This gene is located in a cluster with two related genes on chromosome 12. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2012]

ACMG classification

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.95
