Genes affected
LLGL2 (HGNC:6629): (LLGL scribble cell polarity complex component 2) The lethal (2) giant larvae protein of Drosophila plays a role in asymmetric cell division, epithelial cell polarity, and cell migration. This human gene encodes a protein similar to lethal (2) giant larvae of Drosophila. In fly, the protein's ability to localize cell fate determinants is regulated by the atypical protein kinase C (aPKC). In human, this protein interacts with aPKC-containing complexes and is cortically localized in mitotic cells. Alternative splicing results in multiple transcript variants encoding different isoforms.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 11, 2021The c.113T>C (p.L38P) alteration is located in exon 3 (coding exon 2) of the LLGL2 gene. This alteration results from a T to C substitution at nucleotide position 113, causing the leucine (L) at amino acid position 38 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
