Genes affected

ANKLE2 (HGNC:29101): (ankyrin repeat and LEM domain containing 2) This gene encodes a member of the LEM family of inner nuclear membrane proteins. The encoded protein functions as a mitotic regulator through postmitotic formation of the nuclear envelope. Mutations in this gene cause morphology defects in the nuclear envelope and BAF hyperphosphorylation. [provided by RefSeq, Mar 2014]

ANKLE2 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 12-132734559-G-C is Pathogenic according to our data. Variant chr12-132734559-G-C is described in ClinVar as [Likely_pathogenic]. Clinvar id is 218246.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP4: Computational evidence support a benign effect (MetaRNN=0.30575043). . Strength limited to SUPPORTING due to the PP5.
