Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 22, 2022The c.496G>A (p.A166T) alteration is located in exon 7 (coding exon 6) of the TMEM104 gene. This alteration results from a G to A substitution at nucleotide position 496, causing the alanine (A) at amino acid position 166 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
