Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2022The c.140C>T (p.P47L) alteration is located in exon 4 (coding exon 3) of the PLSCR4 gene. This alteration results from a C to T substitution at nucleotide position 140, causing the proline (P) at amino acid position 47 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
