Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 28, 2024The c.353C>G (p.S118C) alteration is located in exon 2 (coding exon 1) of the TMEM121 gene. This alteration results from a C to G substitution at nucleotide position 353, causing the serine (S) at amino acid position 118 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
