**What it does**

Assuming you have defined the familial relationships between samples when
loading your VCF into GEMINI, you can use this tool to identify candidate genes
and variants that explain the inheritance pattern of a phenotype of interest.

**Inheritance pattern detection rules**

*Autosomal recessive*

Criteria:

- all affected must be hom_alt
- [affected] no unaffected can be hom_alt (can be unknown)
- [default] if parents exist they must be unaffected and het for all affected kids
- [default] if there are no affecteds that have a parent, a warning is issued.

If ``--lenient`` is specified, the 2 criteria prefixed with “[default]” are not
applied.

If ``--allow-unaffected`` is specified, the criterion prefixed with
“[affected]” is not enforced.

----

*Autosomal dominant*

Criteria:

- All affecteds must be het
- [affected] No unaffected can be het or homalt (can be unknown)
- de_novo mutations are not auto_dom (at least not in the first generation)
- At least 1 affected must have 1 affected parent (or have no parents).
- If no affected has a parent, a warning is issued.
- [default] All affecteds must have parents with known phenotype.
- [default] All affected kids must have at least 1 affected parent

If ``--lenient`` is specified, the criteria prefixed with “[default]” are not
enforced.

If ``--allow-unaffected`` is specified, the criterion prefixed with
“[affected]” is not enforced.

Note that, for autosomal dominant, ``--lenient`` allows singleton affecteds to
be used to meet the ``--min-kindreds`` requirement if they are HET.

If there is incomplete penetrance in the kindred (unaffected obligate carriers),
these individuals currently must be coded as having unknown phenotype or as
being affected.

----

*X-linked recessive*

Criteria:

- Affected females must be HOM_ALT
- Unaffected females are HET or HOM_REF
- Affected males are not HOM_REF
- Unaffected males are HOM_REF

Note: Pseudo-autosomal regions are not accounted for by the tool.

----

*X-linked dominant*

Criteria:

- Affected males are HET or HOM_ALT
- Affected females must be HET
- Unaffecteds must be HOM_REF
- girls of affected dad must be affected
- boys of affected dad must be unaffected
- mothers of affected males must be het (and affected)
- at least 1 parent of affected females must be het (and affected).

Note: Pseudo-autosomal regions are not accounted for by the tool.

*De-novo mutations*

Criteria:

- all affected must be het
- [affected] all unaffected must be homref or homalt
- at least 1 affected kid must have unaffected parents
- [default] if an affected has affected parents, it’s not de_novo
- [default] all affected kids must have unaffected (or no) parents
- [default] warning if none of the affected samples have parents.

The last 3 items, prefixed with [default] can be turned off with ``--lenient``.

If ``--allow-unaffected`` is specified, then the criterion prefixed [affected]
is not enforced.

----

*X-linked de-novo mutations*

Criteria:

- affected female child must be het
- affected male child must be hom_alt (or het)
- parents should be unaffected and hom_ref

Note: Pseudo-autosomal regions are not accounted for by the tool.

*Compound heterozygosity*

Unlike canonical recessive sites where the same recessive allele is inherited
from both parents at the *same* site in the gene, compound heterozygosity
occurs when the individual’s phenotype is caused by two heterozygous recessive
alleles at *different* sites in a particular gene.

To detect compound heterozygosity, the tool looks for two heterozygous variants
impacting the same gene at different loci. The complicating factor is that this
is a case of *recessive* inheritance and as such, we must also require that the
consequential alleles at each heterozygous site were inherited on different
chromosomes (one from each parent). Hence, where possible, the tool will phase
by transmission.

Criteria (default):

- All affected individuals must be heterozygous at both sites.
- No unaffected can be homozygous alterate at either site.
- Neither parent of an affected sample can be homozygous reference at both
  sites.
- If any unphased-unaffected is het at both sites, the site will be given lower
  priority.
- No phased-unaffected can be heterozygous at both sites.

  a. ``--allow-unaffected`` keeps sites where a phased unaffected shares the
     het-pair
  b. unphased, unaffected that share the het pair are counted and reported for
     each candidate pair.
- Candidates where an affected from the same family does NOT share the same het
  pair are removed.
- Sites are automatically phased by transmission when parents are present in
  order to remove false positive candidates.
  
  If data from one or both parents are unavailable and the child’s data was not
  phased prior to loading into GEMINI, all comp_het variant pairs will
  automatically be given at most priority == 2. If there’s only a single parent
  and both the parent and the affected are HET at both sites, the candidate
  will have priority 3.
  
Criteria (``--pattern-only``):

- Kid must be HET at both sites.
- Kid must have alts on different chromosomes.
- Neither parent can be HOM_ALT at either site.
- If either parent is phased at both sites and matches the kid, it’s excluded.
- When the above criteria are met, and both parents and kid are phased or
  parents are HET at different sites, the priority is 1.
- If either parent is HET at both sites, priority is reduced.
- If both parents are not phased, the priority is 2.
- For every parent that’s a het at both sites, the priority is incremented by 1.
- The priority in a family is the minimum found among all kids.

*Violation of Mendelian laws*

The tool can be used to detect the following kinds of non-Mendelian patterns:

- loss of heterozygosity (LOH) events
- de-novo mutations
- implausible de-novo mutations
- potential cases of uniparental disomy

Criteria:

- LOH: child and one parent are opposite homozygotes; other parent is HET
- plausible de novo: kid is het. parents are same homozygotes
- implausible de novo: kid is homozygote. parents are same homozygotes and opposite to kid.
- uniparental disomy: parents are opposite homozygotes; kid is homozygote
