Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 25, 2024The c.928C>T (p.R310C) alteration is located in exon 6 (coding exon 4) of the NXPE1 gene. This alteration results from a C to T substitution at nucleotide position 928, causing the arginine (R) at amino acid position 310 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
