Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 28, 2023The c.704C>A (p.S235Y) alteration is located in exon 6 (coding exon 6) of the TMEM38A gene. This alteration results from a C to A substitution at nucleotide position 704, causing the serine (S) at amino acid position 235 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
