Genes affected
SYNPO2 (HGNC:17732): (synaptopodin 2) Enables alpha-actinin binding activity and filamin binding activity. Involved in positive regulation of actin filament bundle assembly; positive regulation of cell migration; and regulation of Rho-dependent protein serine/threonine kinase activity. Located in several cellular components, including Z disc; focal adhesion; and stress fiber. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 30, 2022The c.328G>T (p.G110W) alteration is located in exon 3 (coding exon 3) of the SYNPO2 gene. This alteration results from a G to T substitution at nucleotide position 328, causing the glycine (G) at amino acid position 110 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
