Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 30, 2023The c.1262C>G (p.S421C) alteration is located in exon 11 (coding exon 11) of the HSPA4 gene. This alteration results from a C to G substitution at nucleotide position 1262, causing the serine (S) at amino acid position 421 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
