Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 11, 2023The c.440A>C (p.H147P) alteration is located in exon 4 (coding exon 3) of the TMEM45B gene. This alteration results from a A to C substitution at nucleotide position 440, causing the histidine (H) at amino acid position 147 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
