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]

Ambry Genetics

Mar 16, 2022

The c.1162A>T (p.N388Y) alteration is located in exon 4 (coding exon 4) of the SYNPO2 gene. This alteration results from a A to T substitution at nucleotide position 1162, causing the asparagine (N) at amino acid position 388 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
