Broad Center for Mendelian Genomics, Broad Institute of MIT and Harvard RCV002247705 SCV002507098 likely pathogenic Brain small vessel disease 1 with or without ocular anomalies 2022-05-04 criteria provided, single submitter curation The heterozygous p.Gly843Arg variant in COL4A1 was identified by our study in 1 individual with brain small vessel disease 1 with or without ocular anomalies, also known as porencephaly 1. Trio exome analysis showed this variant to be de novo. The variant has not been previously reported in individuals with porencephaly 1 and was absent from large population studies. Computational prediction tools and conservation analyses suggest that this variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, although additional studies are required to fully establish its clinical significance, this variant is likely pathogenic. ACMG/AMP Criteria applied: PS2, PM2, PP3 (Richards 2015).
