Variant 19-55274469-C-T details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_012267.5(HSPBP1):c.569G>A(p.Arg190His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000818 in 1,589,100 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. R190S) has been classified as Uncertain significance.

The c.569G>A (p.R190H) alteration is located in exon 4 (coding exon 3) of the HSPBP1 gene. This alteration results from a G to A substitution at nucleotide position 569, causing the arginine (R) at amino acid position 190 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
