Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 6P and 4B. PM5 PP3_Strong BS2

The NM_144605.5(SEPTIN12):​c.589G>T​(p.Asp197Tyr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000547 in 1,461,748 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D197N) has been classified as Pathogenic.

Genes affected

SEPTIN12 (HGNC:26348): (septin 12) This gene encodes a guanine-nucleotide binding protein and member of the septin family of cytoskeletal GTPases. Septins play important roles in cytokinesis, exocytosis, embryonic development, and membrane dynamics. Multiple transcript variants encoding different isoforms have been found for this gene.

ENSG00000285952 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM5: Other missense variant is known to change same aminoacid residue: Variant chr16-4783690-C-T is described in Lovd as [Pathogenic].
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.995
• BS2: High AC in GnomAdExome4 at 8 AD gene.
