Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_001367975.1(BTG4):c.329A>G(p.His110Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000651 in 1,382,738 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/21 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. H110Q) has been classified as Uncertain significance.

Genes affected

BTG4 (HGNC:13862): (BTG anti-proliferation factor 4) The protein encoded by this gene is a member of the BTG/Tob family. This family has structurally related proteins that appear to have antiproliferative properties. This encoded protein can induce G1 arrest in the cell cycle. [provided by RefSeq, Jul 2008]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.329A>G (p.H110R) alteration is located in exon 4 (coding exon 3) of the BTG4 gene. This alteration results from a A to G substitution at nucleotide position 329, causing the histidine (H) at amino acid position 110 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
