Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 10, 2023The c.626C>T (p.T209M) alteration is located in exon 2 (coding exon 2) of the TMEM132C gene. This alteration results from a C to T substitution at nucleotide position 626, causing the threonine (T) at amino acid position 209 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
