Variant 1-161524936-C-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP3_Moderate

The NM_002155.5(HSPA6):c.278C>A(p.Pro93His) variant causes a missense change. The variant allele was found at a frequency of 0.00000657 in 152,110 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P93T) has been classified as Uncertain significance.

The c.278C>A (p.P93H) alteration is located in exon 1 (coding exon 1) of the HSPA6 gene. This alteration results from a C to A substitution at nucleotide position 278, causing the proline (P) at amino acid position 93 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
