Genes affected
MAPT (HGNC:6893): (microtubule associated protein tau) This gene encodes the microtubule-associated protein tau (MAPT) whose transcript undergoes complex, regulated alternative splicing, giving rise to several mRNA species. MAPT transcripts are differentially expressed in the nervous system, depending on stage of neuronal maturation and neuron type. MAPT gene mutations have been associated with several neurodegenerative disorders such as Alzheimer's disease, Pick's disease, frontotemporal dementia, cortico-basal degeneration and progressive supranuclear palsy.

ACMG classification
Classification made for transcript
Verdict is Likely_pathogenic. Variant got 9 ACMG points.
PM2
?
Very rare variant in population databases, with high coverage;
PP5
?
Variant 17-46010405-G-A is Pathogenic according to our data. Variant chr17-46010405-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 98218.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr17-46010405-G-A is described in Lovd as [Pathogenic].
BP4
?
Computational evidence support a benign effect (BayesDel_noAF=-0.32).. Strength limited to SUPPORTING due to the PP5.
