chrX-8534382-C-T

Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 4P and 12B. PP3_StrongBP6_Very_StrongBS2

The NM_000216.4(ANOS1):​c.1921G>A​(p.Gly641Arg) variant causes a missense change. The variant allele was found at a frequency of 0.0000513 in 1,208,877 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 19 hemizygotes in GnomAD. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Uncertain significance in ClinVar. Synonymous variant affecting the same amino acid position (i.e. G641G) has been classified as Uncertain significance.

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]
ANOS1 Gene-Disease associations (from GenCC):
  • hypogonadotropic hypogonadism 1 with or without anosmia
    Inheritance: XL Classification: DEFINITIVE, STRONG Submitted by: Labcorp Genetics (formerly Invitae), ClinGen
  • Kallmann syndrome
