Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2023The c.98C>T (p.S33L) alteration is located in exon 2 (coding exon 2) of the TMEM132B gene. This alteration results from a C to T substitution at nucleotide position 98, causing the serine (S) at amino acid position 33 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
