Genes affected
SPTAN1 (HGNC:11273): (spectrin alpha, non-erythrocytic 1) Spectrins are a family of filamentous cytoskeletal proteins that function as essential scaffold proteins that stabilize the plasma membrane and organize intracellular organelles. Spectrins are composed of alpha and beta dimers that associate to form tetramers linked in a head-to-head arrangement. This gene encodes an alpha spectrin that is specifically expressed in nonerythrocytic cells. The encoded protein has been implicated in other cellular functions including DNA repair and cell cycle regulation. Mutations in this gene are the cause of early infantile epileptic encephalopathy-5. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Sep 2010]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.043668926).
BP6
Variant 9-128608962-A-G is Benign according to our data. Variant chr9-128608962-A-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 196941.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=4, Benign=2, Uncertain_significance=1}.
BS1
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.000387 (59/152290) while in subpopulation NFE AF= 0.000662 (45/68012). AF 95% confidence interval is 0.000508. There are 0 homozygotes in gnomad4. There are 29 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
BS2

Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
