Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 13, 2024The c.1348G>A (p.A450T) alteration is located in exon 11 (coding exon 11) of the HSPA12A gene. This alteration results from a G to A substitution at nucleotide position 1348, causing the alanine (A) at amino acid position 450 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
