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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2022The c.638C>T (p.A213V) alteration is located in exon 3 (coding exon 3) of the PLEKHG4 gene. This alteration results from a C to T substitution at nucleotide position 638, causing the alanine (A) at amino acid position 213 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
