desmoglein 4

ENSG00000175065UniProt: Q86SJ6

A component of desmosome cell-cell junctions which are required for positive regulation of cellular adhesion (By similarity). Coordinates the transition from proliferation to differentiation in hair follicle keratinocytes (By similarity). Plays a role in moderating lymphocyte migration to inflamed skin and maintaining homeostasis of the epidermal inflammatory response (By similarity)

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

Typical tolerance to LoF variation

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.
