Feb 14, 2023

The c.334A>T (p.T112S) 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 334, causing the threonine (T) at amino acid position 112 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
