What condition is associated with CFH p.Gln925Ter (c.2773C>T)?

CFH p.Gln925Ter (c.2773C>T) is associated with atypical hemolytic-uremic syndrome (ClinVar).

How common is CFH p.Gln925Ter (c.2773C>T) in the general population?

CFH p.Gln925Ter (c.2773C>T) is very rare (popmax 8.48e-05%, nfe) (gnomAD).

How is Atypical hemolytic uremic syndrome inherited?

Typically Autosomal dominant, Autosomal recessive (Orphanet). A genetic counselor can assess individual risk for a family.

Computational evidence

Protein change
Missense predictors do not apply to this variant type; conservation carries the signal.
Consequence	nonsense (stop-gain)	predicted loss-of-function in a LoF-intolerant gene
NMD	predicted	premature termination codon in exon 17 of 22
Splicing
SpliceAI	—	not assessed · no allele here is in the release
Pangolin	Δ0.22	loss · gain 0.00 · not in the SpliceAI release · independent
Constraint at this position
Conservation	phyloP -0.064	GERP 1
Overall
CADD	36.0	PHRED · no single calibrated threshold — expert panels disagree

Predicted loss-of-function is descriptive, not an applied PVS1 code.

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
