Renal and urinary tract disorders

Gene: ANOS1

Comment on mode of inheritance: Updating the MOI to X-LINKED: hemizygous mutation in males, biallelic mutations in females. This MOI has proposed by 2 reviewers and agrees with that found in OMIM. PMID: 15001591 - reports only male cases with ANOS1 variants, with female carriers, PMID: 11297579 - reports male cases and states that obligate female carriers in families with KAL mutations have no discernible phenotype.

Red List (low evidence)

Although unilateral renal agenesis is seen in a subset of individuals with Kallmann syndrome due to variants in ANOS1, there is little evidence that this is associated with impaired renal function in childhood. PMID:9719154 reports overt renal failure in one adult with a contiguous deletion involving KAL1, and evidence of impaired renal function in a second adult with a clinical diagnosis of Kallmann syndrome. Both had unilateral renal agenesis.

Mode of inheritance
X-LINKED: hemizygous mutation in males, biallelic mutations in females

added new-gene-name tag, new symbol is ANOS1

Created: 27 Feb 2017, 1:55 p.m.

Comment when marking as ready: Associated with phenotype in OMIM, not in G2P. Numerous variants reported

Created: 4 Aug 2016, 2:03 p.m.

Comment on list classification: Gene added by reviewer. The new HGNC-approved symbol for this gene is ANOS1 (for genome build 38).

Comment on list classification: Two reviewers agree this gene should be green.

Green List (high evidence)

Numerous publications show that X-linked Kallman syndrome (i.e. KAL1 mutant) hemizygous males have a 20-30% risk of being born with a single kidney.

Mode of inheritance
X-LINKED: hemizygous mutation in males, monoallelic mutations in females may cause disease (may be less severe, later onset than males)
