Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 23, 2023The c.536A>G (p.Y179C) alteration is located in exon 9 (coding exon 8) of the TMEM40 gene. This alteration results from a A to G substitution at nucleotide position 536, causing the tyrosine (Y) at amino acid position 179 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
