not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2024The 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. -
