Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2023The c.178G>A (p.V60I) alteration is located in exon 3 (coding exon 3) of the DNAJC27 gene. This alteration results from a G to A substitution at nucleotide position 178, causing the valine (V) at amino acid position 60 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
