C1ORF50

Chr 1

chromosome 1 open reading frame 50

The C1ORF50 protein enables identical protein binding activity, but its specific cellular function remains poorly characterized. This gene shows low constraint against loss-of-function variants (pLI = 0.03, LOEUF = 0.94), suggesting tolerance to functional disruption. Currently, no established Mendelian diseases have been definitively linked to C1ORF50 mutations in clinical practice.
