Sydney Genome Diagnostics, Children's Hospital Westmead RCV001328287 SCV001449238 uncertain significance Alport syndrome 2018-10-24 no assertion criteria provided clinical testing This patient is homozygous for a variant of unknown clinical significance (VOUS), c.4462G>C p.(Gly1488Arg), in the COL4A3 gene. To our knowledge, this variant has not been previously reported in the literature and no frequency data is available. c.4462 is the last base of exon 48, and is located in the C-terminal domain of the protein. In silico analysis (Alamut Visual v2.6) using PolyPhen2, SIFT, Align GVGD, KD4v and Mutation Taster all suggest that this variant is likely to be a pathogenic variant. Alamut Visual 2.6 is also inconclusive regarding the splicing effect of this variant.
