not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2022The c.377G>A (p.C126Y) alteration is located in exon 3 (coding exon 3) of the TMEM196 gene. This alteration results from a G to A substitution at nucleotide position 377, causing the cysteine (C) at amino acid position 126 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
