ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), MAST3. . Gene score misZ 4.1363 (greater than the threshold 3.09). Trascript score misZ 3.5232 (greater than threshold 3.09). GenCC has associacion of gene with developmental and epileptic encephalopathy 108.
BP4
Computational evidence support a benign effect (MetaRNN=0.09143233).
BS2
High AC in GnomAdExome4 at 20 AD gene.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 18, 2023The c.2926G>A (p.V976I) alteration is located in exon 23 (coding exon 23) of the MAST3 gene. This alteration results from a G to A substitution at nucleotide position 2926, causing the valine (V) at amino acid position 976 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
