Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2023The c.625A>T (p.I209L) alteration is located in exon 2 (coding exon 1) of the TMEM121 gene. This alteration results from a A to T substitution at nucleotide position 625, causing the isoleucine (I) at amino acid position 209 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
