Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 29, 2024The c.371A>T (p.K124M) alteration is located in exon 2 (coding exon 2) of the TMEM132C gene. This alteration results from a A to T substitution at nucleotide position 371, causing the lysine (K) at amino acid position 124 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
