Embryonic lethal - presence of a pathogenic variant or variants is not compatible with life. The penetrance must be complete.
Severe - presence of a pathogenic variant or variant(s) results in significantly reduced fitness. The penetrance must be complete or high.
Moderate - significant morbidity or mortality due to clinical features, but fitness may not be reduced, or penetrance is reduced.
Mild - Presence of a variant or variant(s) is not associated with reduced fitness, no significant morbidity or mortality, and/or penetrance is low.
None - presence of a variant results in no phenotype. An example is recessive disorders in which no phenotype is reported in carriers.

- The @GENE@ is associated with @inheritance pattern@ @condition@, which is characterized by @clinical features@ (PMIDs).

- Variable expression or severity:
The severity and expressivity of the disorder is highly variable, even within families.
- If multiple conditions associated with the gene:
It has also been associated with @inheritance pattern@ @condition@, which is characterized by @clinical features@ (PMIDs).

- Limited evidence gene: The PCNA gene has been reported in individuals with early onset autosomal recessive ataxia (PMID: 33426167, 24911150), however, evidence supporting this gene-dsiease relationship is limited
