Childhood solid tumours v2.8 GPR161 Arina Puzriakova gene: GPR161 was added
gene: GPR161 was added to Tumour predisposition - childhood onset. Sources: Literature
Mode of inheritance for gene: GPR161 was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown

Phenotypes for gene: GPR161 were set to Medulloblastoma predisposition
Review for gene: GPR161 was set to GREEN
Added comment: PMID: 31609649 (2020) - Heterozygous germline variants were identified in 6 unrelated patients with infant-onset sonic hedgehog medulloblastoma (median age, 1.5 years). No additional germline or somatic driver events were detected. 5/6 cases demonstrated biallelic inactivation of GPR151 as a result of a somatic copy-neutral loss of heterozygosity event on chromosome 1q. This event was absent among GPR161 wild-type medulloblastoma tumours.

PMID: 29386106 (2018) - Loss of Gpr161 activity was consistent with medulloblastoma pathogenesis in a mouse model, where Gpr161 deletion increased downstream activity of the sonic hedgehog pathway. Earlier deletion of Gpr161 during embryogenesis increased tumour incidence and severity.
