Abstract

Gestational vitamin A (retinol) deficiency poses a risk for ocular birth defects and blindness. We identified missense mutations in RBP4, encoding serum retinol binding protein, in three families with eye malformations of differing severity, including bilateral anophthalmia. The mutant phenotypes exhibit dominant inheritance, but incomplete penetrance. Maternal transmission significantly increases the probability of phenotypic expression. RBP normally delivers retinol from hepatic stores to peripheral tissues, including the placenta and fetal eye. The disease mutations greatly reduce retinol binding to RBP, yet paradoxically increase the affinity of RBP for its cell surface receptor, STRA6. By occupying STRA6 nonproductively, the dominant-negative proteins disrupt vitamin A delivery from wild-type proteins within the fetus, but also, in the case of maternal transmission, at the placenta. These findings establish a previously uncharacterized mode of maternal inheritance, distinct from imprinting and oocyte-derived mRNA, and define a group of hereditary disorders plausibly modulated by dietary vitamin A.

  • Pathogenic variants in RBP4 lead to reduced plasma RBP4 and all-trans-retinol concentrations and are associated with night blindness, microphthalmia, anophthalmia, coloboma, retinal dystrophy, and acne vulgaris.

    “Pathogenic variants in RBP4 gene lead to reduced plasma RBP4 and all-trans-retinol concentrations and are associated with night blindness [34,169,170,171], microphthalmia [171,172], anophthalmia [172], coloboma [34,170,172], retinal dystrophy [34,169,170,171,173] and acne vulgaris [34,170,173].”

    From The Role of Vitamin A in Retinal Diseases (2022) · cites this paper as [172]

    The Results (page unavailable) link RBP4 variants to microphthalmia, anophthalmia and coloboma, and report reduced fasting serum vitamin A in three carriers. But they say plasma RBP was within the normal range in carriers of the variants studied; reduced RBP is reported for other RBP4 variants. The Discussion (page unavailable) also reports night blindness and retinal dystrophy with total RBP4 loss, while the paper does not establish an association with acne vulgaris. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
