Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 20, 2021The c.14G>A (p.G5D) alteration is located in exon 1 (coding exon 1) of the TMEM132C gene. This alteration results from a G to A substitution at nucleotide position 14, causing the glycine (G) at amino acid position 5 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
