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]

The c.2438T>G (p.F813C) alteration is located in exon 14 (coding exon 14) of the SYNE3 gene. This alteration results from a T to G substitution at nucleotide position 2438, causing the phenylalanine (F) at amino acid position 813 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
