Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 02, 2021The c.932C>T (p.S311L) alteration is located in exon 2 (coding exon 1) of the TMEM121 gene. This alteration results from a C to T substitution at nucleotide position 932, causing the serine (S) at amino acid position 311 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
