Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 27, 2024The c.1213G>C (p.A405P) alteration is located in exon 10 (coding exon 10) of the TMEM44 gene. This alteration results from a G to C substitution at nucleotide position 1213, causing the alanine (A) at amino acid position 405 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
