TMEM102

Chr 17

transmembrane protein 102

Also known as: CBAP, D2B

NCBI Gene: 284114ENSG00000181284UniProt: Q8N9M5

Involved in regulation of mitochondrial outer membrane permeabilization involved in apoptotic signaling pathway; response to cytokine; and signal transduction. Acts upstream of or within positive regulation of T cell migration and positive regulation of cell adhesion. Located in cell surface. Part of protein-containing complex.

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.
