Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_152592.6(SYNE3):c.2711C>T(p.Pro904Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000353 in 1,612,546 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P904S) has been classified as Uncertain significance.

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.2711C>T (p.P904L) 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 2711, causing the proline (P) at amino acid position 904 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
