Variant 10-116674831-T-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Likely benign. Variant got -4 ACMG points: 0P and 4B. BP4_Strong

The NM_025015.3(HSPA12A):c.1978A>G(p.Ile660Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000186 in 1,613,308 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. I660T) has been classified as Uncertain significance.

The c.1978A>G (p.I660V) alteration is located in exon 12 (coding exon 12) of the HSPA12A gene. This alteration results from a A to G substitution at nucleotide position 1978, causing the isoleucine (I) at amino acid position 660 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
