sorting nexin 20

Also known as: SLIC1

NCBI Gene: 124460ENSG00000167208UniProt: Q7Z614

SNX20 interacts with the cytoplasmic domain of PSGL1 (SELPLG; MIM 600738) and cycles PSGL1 into endosomes.[supplied by OMIM, Feb 2010]

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.

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.
