Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 11, 2024The c.520G>C (p.A174P) alteration is located in exon 8 (coding exon 6) of the TMEM150B gene. This alteration results from a G to C substitution at nucleotide position 520, causing the alanine (A) at amino acid position 174 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
