Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 03, 2023The c.410G>A (p.R137Q) alteration is located in exon 2 (coding exon 2) of the TMEM132C gene. This alteration results from a G to A substitution at nucleotide position 410, causing the arginine (R) at amino acid position 137 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
