Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 29, 2024The c.497C>T (p.A166V) alteration is located in exon 2 (coding exon 2) of the MAZ gene. This alteration results from a C to T substitution at nucleotide position 497, causing the alanine (A) at amino acid position 166 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
