Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_133491.5(SAT2):​c.25G>A​(p.Ala9Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000049 in 1,613,184 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A9D) has been classified as Uncertain significance.

Genes affected
SAT2 (HGNC:23160): (spermidine/spermine N1-acetyltransferase family member 2) Enables diamine N-acetyltransferase activity and identical protein binding activity. Involved in polyamine metabolic process. Located in extracellular exosome. [provided by Alliance of Genome Resources, Apr 2022]
SHBG (HGNC:10839): (sex hormone binding globulin) This gene encodes a steroid binding protein that was first described as a plasma protein secreted by the liver but is now thought to participate in the regulation of steroid responses. The encoded protein transports androgens and estrogens in the blood, binding each steroid molecule as a dimer formed from identical or nearly identical monomers. Polymorphisms in this gene have been associated with polycystic ovary syndrome and type 2 diabetes mellitus. Alternative splicing results in multiple transcript variants.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 31, 2023The c.25G>A (p.A9T) alteration is located in exon 1 (coding exon 1) of the SAT2 gene. This alteration results from a G to A substitution at nucleotide position 25, causing the alanine (A) at amino acid position 9 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
