Variant summary

Our verdict is Benign. Variant got -7 ACMG points: 1P and 8B. PP2BP4_ModerateBP6_ModerateBS2

The NM_001069.3(TUBB2A):c.1330G>A(p.Glu444Lys) variant causes a missense change. The variant allele was found at a frequency of 0.00000867 in 1,614,116 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E444V) has been classified as Benign.

Genes affected

TUBB2A (HGNC:12412): (tubulin beta 2A class IIa) Microtubules, key participants in processes such as mitosis and intracellular transport, are composed of heterodimers of alpha- and beta-tubulins. The protein encoded by this gene is a beta-tubulin. Defects in this gene are associated with complex cortical dysplasia with other brain malformations-5. Two transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jul 2015]
