Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 15, 2021The c.955T>A (p.S319T) alteration is located in exon 2 (coding exon 1) of the TMEM200A gene. This alteration results from a T to A substitution at nucleotide position 955, causing the serine (S) at amino acid position 319 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
