Genes affected

ANOS1 (HGNC:6211): (anosmin 1) Mutations in this gene cause the X-linked Kallmann syndrome. The encoded protein is similar in sequence to proteins known to function in neural cell adhesion and axonal migration. In addition, this cell surface protein is N-glycosylated and may have anti-protease activity. [provided by RefSeq, Jul 2008]

Nov 08, 2022

The c.409C>G (p.P137A) alteration is located in exon 4 (coding exon 4) of the ANOS1 gene. This alteration results from a C to G substitution at nucleotide position 409, causing the proline (P) at amino acid position 137 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
