Genes affected
SPTB (HGNC:11274): (spectrin beta, erythrocytic) This locus encodes a member of the spectrin gene family. Spectrin proteins, along with ankyrin, play a role in cell membrane organization and stability. The protein encoded by this locus functions in stability of erythrocyte membranes, and mutations in this gene have been associated with spherocytosis type 2, hereditary elliptocytosis, and neonatal hemolytic anemia. Alternatively spliced transcript variants have been described. [provided by RefSeq, Nov 2009]

ACMG classification
Classification made for transcript
Verdict is Uncertain_significance. Variant got 2 ACMG points.
PM2
?
Very rare variant in population databases, with high coverage;
PP5
?
Variant 14-64767300-C-A is Pathogenic according to our data. Variant chr14-64767300-C-A is described in ClinVar as [Pathogenic]. Clinvar id is 12832.Status of the report is no_assertion_criteria_provided, 0 stars.
BP4
?
Computational evidence support a benign effect (BayesDel_noAF=-0.31). . Strength limited to SUPPORTING due to the PP5.
