Genes affected
HSPA12B (HGNC:16193): (heat shock protein family A (Hsp70) member 12B) The protein encoded by this gene contains an atypical heat shock protein 70 (Hsp70) ATPase domain and is therefore a distant member of the mammalian Hsp70 family. This gene may be involved in susceptibility to atherosclerosis. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2015]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 31, 2023The c.884G>A (p.R295H) alteration is located in exon 9 (coding exon 8) of the HSPA12B gene. This alteration results from a G to A substitution at nucleotide position 884, causing the arginine (R) at amino acid position 295 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
