Variant summary

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

The ENST00000259667.6(HINT2):c.11C>G(p.Ala4Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000271 in 1,474,274 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 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. A4V) has been classified as Likely benign.

Jan 23, 2024

The c.11C>G (p.A4G) alteration is located in exon 1 (coding exon 1) of the HINT2 gene. This alteration results from a C to G substitution at nucleotide position 11, causing the alanine (A) at amino acid position 4 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
