Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2023The c.299A>T (p.E100V) alteration is located in exon 4 (coding exon 4) of the TMEM87A gene. This alteration results from a A to T substitution at nucleotide position 299, causing the glutamic acid (E) at amino acid position 100 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
