Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 17, 2022The c.656T>C (p.I219T) alteration is located in exon 7 (coding exon 6) of the PLSCR4 gene. This alteration results from a T to C substitution at nucleotide position 656, causing the isoleucine (I) at amino acid position 219 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
