Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 23, 2023The c.946A>T (p.T316S) alteration is located in exon 1 (coding exon 1) of the HSPA2 gene. This alteration results from a A to T substitution at nucleotide position 946, causing the threonine (T) at amino acid position 316 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
