Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 19, 2024The c.811G>A (p.G271S) alteration is located in exon 2 (coding exon 1) of the TMEM200A gene. This alteration results from a G to A substitution at nucleotide position 811, causing the glycine (G) at amino acid position 271 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
