Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_153271.2(SNX33):c.400G>A(p.Gly134Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000128 in 1,563,844 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 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. G134A) has been classified as Likely benign.

Genes affected

SNX33 (HGNC:28468): (sorting nexin 33) The protein encoded by this gene is involved in cytoskeletal reorganization, vesicle trafficking, endocytosis, and mitosis. The encoded protein is essential for the creation of the cleavage furrow during mitosis and for completion of mitosis. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2015]

Collection Method: clinical testing

The c.400G>A (p.G134R) alteration is located in exon 1 (coding exon 1) of the SNX33 gene. This alteration results from a G to A substitution at nucleotide position 400, causing the glycine (G) at amino acid position 134 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
