Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 22, 2022The c.128C>T (p.S43F) 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 128, causing the serine (S) at amino acid position 43 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
