Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 16, 2024The c.403A>G (p.T135A) alteration is located in exon 6 (coding exon 5) of the PLSCR4 gene. This alteration results from a A to G substitution at nucleotide position 403, causing the threonine (T) at amino acid position 135 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
