Variant summary

Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PS1_Moderate PM1 PM2 PP3_Strong PP5

The NM_000186.4(CFH):​c.2876G>A​(p.Cys959Tyr) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another nucleotide change resulting in same amino acid change has been previously reported as Likely pathogenicin UniProt.

Genes affected

CFH (HGNC:4883): (complement factor H) This gene is a member of the Regulator of Complement Activation (RCA) gene cluster and encodes a protein with twenty short consensus repeat (SCR) domains. This protein is secreted into the bloodstream and has an essential role in the regulation of complement activation, restricting this innate defense mechanism to microbial infections. Mutations in this gene have been associated with hemolytic-uremic syndrome (HUS) and chronic hypocomplementemic nephropathy. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Oct 2011]

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PS1: Transcript NM_000186.4 (CFH) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in UniProt
• PM1: In a disulfide_bond (size 25) in uniprot entity CFAH_HUMAN there are 4 pathogenic changes around while only 0 benign (100%) in NM_000186.4
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.99
• PP5: Variant 1-196740712-G-A is Pathogenic according to our data. Variant chr1-196740712-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 16544.Status of the report is no_assertion_criteria_provided, 0 stars.
