Genes affected
PTPN4 (HGNC:9656): (protein tyrosine phosphatase non-receptor type 4) The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This protein contains a C-terminal PTP domain and an N-terminal domain homologous to the band 4.1 superfamily of cytoskeletal-associated proteins. This PTP has been shown to interact with glutamate receptor delta 2 and epsilon subunits, and is thought to play a role in signalling downstream of the glutamate receptors through tyrosine dephosphorylation.

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.18740624).
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0000856 (13/151872) while in subpopulation AFR AF= 0.000291 (12/41306). AF 95% confidence interval is 0.000167. There are 0 homozygotes in gnomad4. There are 7 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High AC in GnomAd4 at 13 AD gene.

Collection Method: clinical testing

The c.53C>T (p.S18L) alteration is located in exon 2 (coding exon 1) of the PTPN4 gene. This alteration results from a C to T substitution at nucleotide position 53, causing the serine (S) at amino acid position 18 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
