The c.2762A>T (p.H921L) alteration is located in exon 12 (coding exon 12) of the TXNDC11 gene. This alteration results from a A to T substitution at nucleotide position 2762, causing the histidine (H) at amino acid position 921 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
