Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 19, 2024The c.1062T>A (p.D354E) alteration is located in exon 9 (coding exon 9) of the TMEM44 gene. This alteration results from a T to A substitution at nucleotide position 1062, causing the aspartic acid (D) at amino acid position 354 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
