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]

The c.1004A>G (p.Q335R) alteration is located in exon 3 (coding exon 3) of the SYNPO2 gene. This alteration results from a A to G substitution at nucleotide position 1004, causing the glutamine (Q) at amino acid position 335 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
