Neuberg Centre For Genomic Medicine, NCGM RCV001808444 SCV005439052 likely pathogenic 3MC syndrome 1 criteria provided, single submitter clinical testing The stop gained variant c.1576C>T p.Arg526Ter in the MASP1 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant is reported with the allele frequency 0.004% in the gnomAD Exomes. It has been submitted to ClinVar as Likely Pathogenic/ Uncertain significance. This variant is predicted to cause loss of normal protein function through protein truncation. Loss of function variants has been previously reported to be disease-causing Degn et al., 2012. For these reasons, this variant has been classified as Likely Pathogenic. In the absence of another reportable variant, the molecular diagnosis is not confirmed.
