Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 08, 2023The c.103G>T (p.G35C) alteration is located in exon 1 (coding exon 1) of the TMEM183A gene. This alteration results from a G to T substitution at nucleotide position 103, causing the glycine (G) at amino acid position 35 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
