Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2022The c.778T>G (p.S260A) alteration is located in exon 6 (coding exon 5) of the TMEM45B gene. This alteration results from a T to G substitution at nucleotide position 778, causing the serine (S) at amino acid position 260 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
