Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 17, 2021The c.2780C>T (p.A927V) alteration is located in exon 14 (coding exon 11) of the POM121C gene. This alteration results from a C to T substitution at nucleotide position 2780, causing the alanine (A) at amino acid position 927 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
