Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2022The c.503G>T (p.G168V) alteration is located in exon 5 (coding exon 5) of the MVB12A gene. This alteration results from a G to T substitution at nucleotide position 503, causing the glycine (G) at amino acid position 168 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
