Genes affected

PLEKHG4 (HGNC:24501): (pleckstrin homology and RhoGEF domain containing G4) The protein encoded by this gene can function as a guanine nucleotide exchange factor (GEF) and may play a role in intracellular signaling and cytoskeleton dynamics at the Golgi apparatus. Polymorphisms in the region of this gene have been found to be associated with spinocerebellar ataxia in some study populations. Alternative splicing results in multiple transcript variants.

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=3.837583E-6).
• BP6: Variant 16-67284339-A-G is Benign according to our data. Variant chr16-67284339-A-G is described in ClinVar as [Benign]. Clinvar id is 129965.Status of the report is criteria_provided_single_submitter, 1 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.624 is higher than 0.05.
