Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2022The c.743C>T (p.P248L) alteration is located in exon 6 (coding exon 6) of the FBLN7 gene. This alteration results from a C to T substitution at nucleotide position 743, causing the proline (P) at amino acid position 248 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
