Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2021The c.2398G>A (p.V800I) alteration is located in exon 13 (coding exon 10) of the POM121C gene. This alteration results from a G to A substitution at nucleotide position 2398, causing the valine (V) at amino acid position 800 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
