CFAP206

Chr 6AR

cilia and flagella associated protein 206

Also known as: C6orf165, SPGF102, dJ382I10.1

NCBI Gene: 154313ENSG00000272514UniProt: Q8IYR0

Predicted to be involved in regulation of cilium beat frequency; regulation of flagellated sperm motility; and sperm axoneme assembly. Predicted to be located in A axonemal microtubule and motile cilium. Predicted to be part of radial spoke. Predicted to be active in axoneme and ciliary basal body.

Population Genetics & Constraint

gnomAD v4 — loss-of-function & missense intolerance

gnomAD
Tolerant — LoF & missense variants common in population
LoF Constraint?LOEUF (Loss-of-function Observed/Expected Upper bound Fraction) is the upper bound of the 90% CI for LoF OE — the preferred gnomAD v4 metric. Lower = more intolerant to LoF. LOEUF < 0.35 = highly constrained.

Tolerant

Highly tolerant — LoF variants common in population

Missense Constraint?Missense Z-score: standard deviations fewer missense variants observed vs. expected. Z > 3.09 (p < 0.001) = gene does not tolerate missense variation. OE missense < 0.6 is also considered constrained.

Synonymous OE?Control metric — synonymous variants are largely neutral and expected near OE = 1.0. Significant deviation may indicate annotation issues.1.01
