Synonym:	non-rhizomelic chondrodysplasia punctata
Modes of inheritance:	Autosomal recessive inheritance MedGen UID: 141025 •Concept ID: C0441748 • Intellectual Product Source: Orphanet 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). Autosomal dominant inheritance MedGen UID: 141047 •Concept ID: C0443147 • Intellectual Product Source: Orphanet 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. X-linked recessive inheritance MedGen UID: 375779 •Concept ID: C1845977 • Finding Source: Orphanet A mode of inheritance that is observed for recessive traits related to a gene encoded on the X chromosome. In the context of medical genetics, X-linked recessive disorders manifest in males (who have one copy of the X chromosome and are thus hemizygotes), but generally not in female heterozygotes who have one mutant and one normal allele. See: This record X-linked dominant inheritance MedGen UID: 376232 •Concept ID: C1847879 • Finding Source: Orphanet A mode of inheritance that is observed for dominant traits related to a gene encoded on the X chromosome. In the context of medical genetics, X-linked dominant disorders tend to manifest very severely in affected males. The severity of manifestation in females may depend on the degree of skewed X inactivation.

Definition

Non-rhizomelic chondrodysplasia punctata is a form of chondrodysplasia punctata (see this term), a group of diseases in which the common characteristic is bone calcifications near joints from birth. Non-rhizomelic chondrodysplasia punctata is not an entity in itself but covers several diseases with variable clinical findings and modes of transmission. [from ORDO]
