Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 06, 2023The c.205A>G (p.I69V) alteration is located in exon 6 (coding exon 4) of the TMEM150B gene. This alteration results from a A to G substitution at nucleotide position 205, causing the isoleucine (I) at amino acid position 69 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
