Genes affected

LIN7A (HGNC:17787): (lin-7 homolog A, crumbs cell polarity complex component) The protein encoded by this gene is involved in generating and maintaining the asymmetric distribution of channels and receptors at the cell membrane. The encoded protein also is required for the localization of some specific channels and can be part of a protein complex that couples synaptic vesicle exocytosis to cell adhesion in the brain.

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.36).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.797 is higher than 0.05.
