Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 17, 2022The c.128C>T (p.A43V) alteration is located in exon 2 (coding exon 1) of the TMEM187 gene. This alteration results from a C to T substitution at nucleotide position 128, causing the alanine (A) at amino acid position 43 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
