Genes affected
LIN7B (HGNC:17788): (lin-7 homolog B, crumbs cell polarity complex component) Enables protein domain specific binding activity. Predicted to be involved in maintenance of epithelial cell apical/basal polarity; neurotransmitter secretion; and protein localization to basolateral plasma membrane. Predicted to be located in plasma membrane. Predicted to be part of MPP7-DLG1-LIN7 complex. Predicted to be active in basolateral plasma membrane; cell-cell junction; and synapse.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2021The c.150C>G (p.I50M) alteration is located in exon 2 (coding exon 2) of the LIN7B gene. This alteration results from a C to G substitution at nucleotide position 150, causing the isoleucine (I) at amino acid position 50 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
