Genes affected

COL4A5 (HGNC:2207): (collagen type IV alpha 5 chain) This gene encodes one of the six subunits of type IV collagen, the major structural component of basement membranes. Mutations in this gene are associated with X-linked Alport syndrome, also known as hereditary nephritis. Like the other members of the type IV collagen gene family, this gene is organized in a head-to-head conformation with another type IV collagen gene so that each gene pair shares a common promoter. Alternatively spliced transcript variants have been identified for this gene. [provided by RefSeq, Aug 2010]

ACMG classification

Verdict is Pathogenic. Variant got 10 ACMG points.

• PM1: In a compositionally_biased_region Pro residues (size 42) in uniprot entity CO4A5_HUMAN there are 4 pathogenic changes around while only 0 benign (100%) in NM_033380.3
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.995
• PP5: Variant X-108575947-G-A is Pathogenic according to our data. Variant chrX-108575947-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 24292.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chrX-108575947-G-A is described in Lovd as [Pathogenic].
