Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 27, 2022The c.440C>T (p.A147V) 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 440, causing the alanine (A) at amino acid position 147 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
