Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 25, 2024The c.217G>A (p.A73T) alteration is located in exon 4 (coding exon 1) of the TMEM100 gene. This alteration results from a G to A substitution at nucleotide position 217, causing the alanine (A) at amino acid position 73 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
