PLD6
Chr 17phospholipase D family member 6
Also known as: ZUC
PLD6 encodes a phospholipase that cleaves the mitochondrial lipid cardiolipin to regulate mitochondrial fusion and fission dynamics, and also functions as an endonuclease critical for PIWI-interacting RNA biogenesis during spermatogenesis. Mutations cause mitochondrial myopathy and male infertility, with autosomal recessive inheritance. The gene shows tolerance to loss-of-function variation (pLI 0.002, LOEUF 1.76), suggesting complete loss of function may be compatible with survival in some cases.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Mild missense constraint
This gene has evidence for multiple mechanisms of pathogenicity (gain-of-function and dominant-negative). Both the Badonyi & Marsh prediction and the broader genomic evidence point to gain-of-function as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.
Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
