Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 04, 2023The c.263A>G (p.Y88C) alteration is located in exon 4 (coding exon 3) of the PLSCR4 gene. This alteration results from a A to G substitution at nucleotide position 263, causing the tyrosine (Y) at amino acid position 88 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
