Genes affected

SYNE3 (HGNC:19861): (spectrin repeat containing nuclear envelope family member 3) Enables actin filament binding activity and cytoskeleton-nuclear membrane anchor activity. Involved in cytoskeleton organization; establishment of protein localization to membrane; and regulation of cell shape. Located in nuclear membrane. Part of meiotic nuclear membrane microtubule tethering complex. Biomarker of Huntington's disease. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Nov 08, 2022

The c.2710C>T (p.P904S) alteration is located in exon 16 (coding exon 16) of the SYNE3 gene. This alteration results from a C to T substitution at nucleotide position 2710, causing the proline (P) at amino acid position 904 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
