- Milia (HP:0001056): Presence of multiple small cysts containing keratin (skin protein) and presenting as tiny pearly-white bumps just under the surface of the skin. Evidence: TAS. (OMIM:131705)
- Fragile skin (HP:0001030): Skin that splits easily with minimal injury. Evidence: TAS. (OMIM:131705)
- Abnormal blistering of the skin (HP:0008066): The presence of one or more bullae on the skin, defined as fluid-filled blisters more than 5 mm in diameter with thin walls. Evidence: PCS. Frequency: 6/6. Onset: Neonatal onset (HP:0003623). (PMID:9406826)
- Atrophic scars (HP:0001075): Scars that form a depression compared to the level of the surrounding skin because of damage to the collagen, fat or other tissues below the skin. Evidence: TAS. (OMIM:131705)
- Autosomal recessive inheritance (HP:0000007): A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele). Evidence: TAS. (OMIM:131705)
- Nail dystrophy (HP:0008404): Onychodystrophy (nail dystrophy) refers to nail changes apart from changes of the color (nail dyschromia) and involves partial or complete disruption of the various keratinous layers of the nail plate. Evidence: TAS. (OMIM:131705)
- Autosomal dominant inheritance (HP:0000006): A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele. Evidence: PCS. (PMID:9406826)
- Neonatal onset (HP:0003623): Onset of signs or symptoms of disease within the first 28 days of life. Evidence: PCS. Frequency: 6/6. (PMID:9406826)
These phenotypes are associated with the disease transient bullous dermolysis of the newborn (OMIM:131705).
