Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 31, 2022The c.425G>T (p.G142V) alteration is located in exon 4 (coding exon 4) of the YDJC gene. This alteration results from a G to T substitution at nucleotide position 425, causing the glycine (G) at amino acid position 142 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
