Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 10, 2024The c.707C>T (p.A236V) alteration is located in exon 7 (coding exon 7) of the DNAJC27 gene. This alteration results from a C to T substitution at nucleotide position 707, causing the alanine (A) at amino acid position 236 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
