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 GeneticsFeb 22, 2024The c.607C>G (p.L203V) alteration is located in exon 3 (coding exon 3) of the SYNPO2 gene. This alteration results from a C to G substitution at nucleotide position 607, causing the leucine (L) at amino acid position 203 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
