Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2023The c.224T>G (p.L75R) alteration is located in exon 1 (coding exon 1) of the HSPA6 gene. This alteration results from a T to G substitution at nucleotide position 224, causing the leucine (L) at amino acid position 75 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
